The northern lights shine over La Baie in Quebec at 2 a.m. Saturday, in a picture taken by Laurent Silvani. To see more of Silvani's work, check out his Silvani.ca website and his Facebook page.

A slight solar storm ejected from a powerful sunspot sparked northern lights as far south as Colorado on Friday night — and there should be more to come.

The heightened aurora was sparked by a burst of electrically charged particles thrown off from an active spot on the sun known as Region 1748. That region is the one responsible for four powerful X-class flares that blasted out from the sun this week. Region 1748 is just now turning in our direction, and forecasters at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center say it has the potential to throw some hefty storms our way.

Storms from the sun have the potential to disrupt satellite communications and power grids, and in extreme cases, the radiation risk could force airlines to reroute their intercontinental flights to lower latitudes. But Joe Kunches, a spokesman for the prediction center, said experts now have much better capabilities at their command to reduce the risks. And so far, he said, the active sun has been throwing "softballs" at us — at least compared with bigger flare-ups like the Halloween storms of 2003 or the Bastille Day storm of 2000.

The most noticeable effects of recent solar disruptions have come in the form of enhanced auroral displays. SpaceWeather.com reports that faint glows were recorded Friday night in Colorado as well as Vermont, New York, Michigan, Wisconsin, Iowa and Washington state.

Farther north, the fireworks show was significantly brighter. Astrophotographer Laurent Silvani captured some great images from Quebec's Saguenay region, about 100 miles (160 kilometers) north of Quebec City.

"Following a magnetic storm, the aurora borealis was particularly visible in the sky with its waves and colors. A particularly beautiful sight!" he wrote in an email. "Many people from the Saguenay do not know that there are auroras occasionally here. They are surprised to see my pictures every time."

Check out Silvani's website and Facebook page for more.

For additional views of auroral glories — including, yes, some photos of the southern lights as seen from Antarctica —take a spin through SpaceWeather.com's photo gallery. And who knows? You might be able to catch the show yourself over the next couple of nights. Another geomagnetic storm is expected to sweep over Earth's magnetic field on Sunday, according to the Space Weather Prediction Center.

To find out what can be seen from where, keep an eye on the center's Facebook page as well as its Ovation aurora forecast maps. If you're in the aurora zone, the best time to look is after midnight. The best places are far away from city lights, with clear, crisp skies. Got pictures? Share them with us via NBC News' FirstPerson photo upload page.

Talk about dancing with the stars: The glow of the northern lights danced through the night sky this week, thanks to a solar storm that swept past Earth over the past few days. Comet PanSTARRS, which is appearing a little bit farther north in western skies every evening, adds some extra sparkle.

The time around the equinox is considered the peak of the aurora season, because this time of year strikes a balance between the dark skies of winter and the more clement temperatures of summer. And although PanSTARRS may not have panned out the way some of the more optimistic skywatchers might have expected, it's still observable in the Northern Hemisphere — particularly if you're watching with binoculars from a vantage point far from city lights, with a clear view to the western horizon.

Sky & Telescope's PanSTARRS page helps you track the comet day by day, and you can always rely on SpaceWeather.com to have the latest, greatest pictures of PanSTARRS as well as the auroral glow.

For example, French photographer Sylvain Dussans managed to capture both phenomena in one glorious picture, taken from Norway's Senja Island.

Here are a couple more videos of the solar storm and the comet, as seen from Earth and space:

Chad Blakley / Lights Over Lapland

The northern lights shimmer in the skies above Abisko National Park in Sweden on March 3. "In addition to the northern lights, you can also see a massive fireball streak across the sky," photographer Chad Blakley writes. "It was a fantastic night!"

It's prime time for the northern lights, and particularly for the far northern lights.

"I believe I just saw the most amazing aurora display I have ever seen," Chad Blakley, the photographer behind Lights Over Lapland, wrote from Sweden over the weekend. "I would send you more images, but I have to go back outside and take a few more photos first." (You can see the results in the time-lapse video below.)

Places like Sweden and Norway, Iceland and Finland, Alaska and Canada's Northwest Territories are prime viewing areas for the northern lights, because that's where the interactions between Earth's poles and the sun's geomagnetic storms are strongest. The fact that the sun's 11-year activity cycle is close to its predicted maximum should be adding to the show, although the storm activity has been mysteriously low so far. 

There's another factor that makes this month favorable for seeing the northern lights: Experts say that March and September, around the time of the year's two equinoxes, are just right for aurora-watching because the skies stay dark for a relatively long time, and yet the weather is relatively mild. December can get pretty chilly up north, and June is the time of the midnight sun — which is not conducive to seeing the aurora's delicate greenish glow.

Darkness is the key to seeing the aurora, whether you're in Abisko National Park in Sweden, or in Albany, N.Y. Stake out a place that's far from city lights with good northern exposure. The thinner and clearer the air, the better — which means you should be up on a mountain rather than down in a valley. The wee hours of the morning are the best time of night for spotting the northern lights.

If you're not in the prime aurora zone, spotting a good display is a matter of good timing, good luck and location, location, location.

Auroral displays are seldom seen much farther south than the northern tier of U.S. states, but every once in a while there's a strong storm that lights up the skies in America's midsection. To find out when a storm is brewing, check in with SpaceWeather.com, the University of Alaska's Aurora Forecast website and the National Oceanic and Atmospheric Administration's Space Weather Prediction Center, plus the prediction center's Facebook page and its Ovation aurora forecasting app. The Yukon Territory's Northern Lights Centre provides additional tips for aurora-watchers. You can also follow @Aurora_Alerts, @AuroraMax and @AuroraWatch on Twitter. 

If you live too far south to see the lights with your own eyes, don't despair: You'll find plenty of auroral pictures in SpaceWeather.com's gallery, and Vimeo has lots of videos to show you. Got a great picture of the northern (or southern) lights? Feel free to share it via our FirstPerson photo-upload page.

Chad Blakley / Lights Over Lapland

The northern lights vie with a waxing moon over Sweden's Abisko National Park on Monday night.

One look at SpaceWeather.com's aurora gallery will tell you that February has been a very good month for auroral displays in northern latitudes, and an upswing in solar activity promises more to come.

One of the hot spots is Sweden's Abisko National Park, which is the favorite hangout for Chad Blakley of Lights Over Lapland. "We have seen powerful auroras in the sky above Abisko for 13 nights in a row, and it looks like there are more to come!" he wrote in an email Tuesday. "Last night I witnessed one of the finest aurora displays I have seen in many months. February 2013 is turning out to be one of the best months for aurora watching I have ever seen!"

You can get a sense of how Blakley's nights have been going by taking a minute to watch Blakley's time-lapse video below. But don't stop there: I'm also including a time-lapse from Helge Mortensen, a photographer based in Tromso, Norway, and from Oli Haukur and the OZZO Photography team in Iceland.

Scandinavia, Alaska and northern Canada are all hot spots for the northern lights this time of year, even though it gets chilly at night. The auroral displays might dip farther south if we get a nice geomagnetic storm coming our way, and the solar weather outlook suggests that could happen. A new sunspot region known as AR 1678 has cropped up, and SpaceWeather.com says this region could give rise to "a significant solar flare."

Check out the usual places for space weather updates, including the National Oceanic and Atmospheric Administration's Space Weather Prediction Center as well as the center's Facebook page and its Ovation aurora forecast chart. You'll also want to keep tabs on the Canadian Space Agency's AuroraMAX website — and the Lights Over Lapland Facebook page, where you'll find an awesome image of the aurora glowing beside a moon halo.

Thomas Kast

The northern lights glow over a snowy Finnish landscape in a photo taken on the night of Jan. 16-17 by Thomas Kast. Watch the time-lapse video on Vimeo.

"The Blob" from the sun has come and gone, sparking nothing more than beautiful views of the northern lights — and there could be more blobs to come.

This week, the National Oceanic and Atmospheric Administration's Space Weather Prediction Center reported that a "plasma blob" of electrically charged particles was thrown out from the sun in Earth's direction — but that the outburst, also known as a coronal mass ejection or CME, wouldn't disrupt satellite systems or electrical power grids when it swept past us on Thursday.

The blob did register on the geomagnetic scale, but well below hazardous levels, just as the center predicted. And although there were no flashy light shows reported in America's Lower 48 states, the northern lights were dancing in high-latitude regions. Thomas Kast caught his first aurora of the new year in the skies over Rokua in Finland.

Kast said the vantage point for the picture you see here is about 50 miles (80 kilometers) from his home — and the temperatures dipped down to 16 below zero Fahrenheit (-27 degrees Celsius). "I spent more than four hours at that spot," Kast said. "It takes time, but it's so rewarding."

If you like the picture above, you'll love the video version that Kast has just posted to his Vimeo gallery. To see more of Kast's photos, check out his Facebook page as well as his posting to SpaceWeather.com's aurora gallery.

Göran Strand saw this week's auroral show from the Kall area in the Swedish municipality of Åre, where the temperature was 11 below zero F (-24 degrees C). "When we arrived at the location and stepped out of the car, a moose stepped out of the forest and looked at us, and it looked a bit surprised finding us there in the middle of the night," Strand said in an email.

"It turned out to be a fantastic night with a half moon that lit up the landscape in a lovely way," Strand told SpaceWeather.com." In the background you can the mountain Åreskutan, the biggest ski resort in Sweden."

For more astrophotography from Strand, click on over to his Astrofotografen website and his Facebook page.

Goran Strand

Swedish astrophotographer Goran Strand captured this view of an aurora lighting up the night sky above a moonlit landscape. The constellation Orion, the Pleiades and the planet Jupiter also gleam in the skies above.

Stian Rekdal

The northern lights compete with the city lights of Ålesund, Norway, in a picture taken by Stian Rekdal.

Meanwhile, in Norway, Stian Rekdal lucked into a glittering photograph of natural and artificial lights.

"It was taken from the viewpoint of Fjellstua (literal translation, 'the mountain lodge'), which is approximately 400 feet above the town of Ålesund," Rekdal wrote in an email. "Aurorae are not as common here as farther north. This part of Norway is also prone to cloudy weather, further decreasing the odds of spotting them. So last night was a rare treat."

Check out more of Rekdal's aurora imagery at the 500px photo website, or the Vimeo video portal.

The Space Weather Prediction Center says that two more coronal mass ejections are heading toward Earth — but like the earlier plasma blob, these outbursts "are not expected to be very strong." To find out where auroral displays are expected to glow, check NOAA's Ovation chart, the prediction center's website, the University of Alaska Geophysical Institute's aurora indicator or SpaceWeather.com. And if you snap a great picture of the aurora, feel free to share it via the Cosmic Log Facebook page or NBC News' FirstPerson photo upload page.

Update for 3 a.m. ET Jan. 21: Aurora photographer Chad Blakley took the stunning still imagery he captured on Jan. 19 and assembled into this must-see time-lapse video on Vimeo. "The solar blob you wrote about last week has made its way to Earth!" he wrote in an email. For more, check out Blakley's Lights Over Lapland website and Facebook page.

Auroral lights glow in the skies over Sweden's Abisko National Park on Jan. 13.

It might sound scary to hear that a giant blob of solar plasma is heading straight for us, but don't panic: Space weather forecasters say this solar outburst should deliver nothing more than a spectacular show up north.

"We're not going to be in for a big disturbance," said Norm Cohen, senior forecaster at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center in Colorado. "The northern tier of the United States might be able to see aurorae."

The outburst of electrically charged plasma — also known as a coronal mass ejection, or CME — blasted out from the sun on Jan. 13, sparking a radio blackout. It's taken several days for the blob itself to travel the 93 million miles between the sun and here, but forecasters now expect it to sweep over Earth's magnetic field early to midday Thursday.

When strong solar storms interact with the magnetosphere, they can spark satellite outages and disrupt electric power grids. Fortunately, this one shouldn't be that strong. (In geekspeak, let's just say that the maximum Kp is expected to reach no higher than 4. NOAA's space weather scale lays out the effects associated with higher Kp levels. Check out the prediction center's Facebook page for space weather updates.)

The most visible effect should be the northern lights generated by the interaction between the electrically charged solar particles and atoms in Earth's upper atmosphere, as explained on the "Causes of Color" website. This week's geomagnetic flare-up should add to what's already been a great week for auroral displays in northern latitudes.

Chad Blakley, a photographer at Sweden's Abisko National Park, sent in the beauty you see above. "It looks like there may be more powerful auroras in the days ahead," Blakley said in an email. "It is a very good time to be an aurora photographer!"

For more of Blakley's beauties, check out the Lights Over Lapland website or the LOL Facebook page.

Glowing reports are coming in from space as well. Here's a picture captured by the Department of Defense's DMSP F-18 OLS low-light imager on Jan. 13. The green outlines show Ireland and Britain down south, and Iceland and Scandinavia up north. The ghostly wisps crossing the frame are the northern lights. It's conceivable that the bright streaks you see in this satellite picture are the same ones visible in Blakley's pictures.

The northern lights show up as ghostly streaks of white in a satellite picture captured on Jan. 13 by a low-light imager on the Defense Department's DMSP F-18 meteorological satellite.

Are there more solar blasts heading our way? SpaceWeather.com notes that a complex sunspot region known as AR1654 is pointing in our direction and has the potential to send more big blobs of plasma our way. But Cohen said the worries about that particular sunspot have been receding.

"It's been fairly quiet in terms of flare production," he said. "If anything, it's beginning to show signs of decay."

In fact, there's been increasing talk that this year's expected peak of the sun's 11-year activity cycle could be relatively wimpy. Cohen said he didn't want to make that sweeping of a prediction — but he did admit that there hasn't been as much disruption as some people might have feared.

"The activity hasn't been all that impressive yet," he said.

Chad Blakley

The green glow of the aurora seems to stretch from horizon to horizon in Chad Blakley's photo from Sweden's Abisko National Park.

Tonight is prime time for the Geminid meteor shower, but there's another kind of spectacle that skywatchers are seeing up north: auroral displays in the Christmas colors of green and red.

The green glow you see above was captured on camera last week by Chad Blakley, the photographer behind Lights Over Lapland in Sweden. "It's aurora season in Abisko National Park," he writes. Blakley runs nightly photo tours in the park when the northern lights are active. To see more of his work, visit the Lights Over Lapland website or Facebook page.

National Geographic photographer Mike Theiss has also been getting some amazing auroral views, thanks to a photo assignment that took him to Whitehorse in Canada's Yukon Territory. Theiss rented a car and drove hundreds of miles farther north to the Arctic Circle. He's been using his Twitter account (@MikeTheiss) to share a series of pictures from his Arctic adventure — including an amazing shot that shows a meteor streak shooting through the auroral lights. You can see that picture below.

We're also including a Christmas bonus: Time-lapse videos from Vimeo and YouTube that incorporate Blakley's and Theiss' pictures. If you're able to, watch them full screen with HD resolution.

For more of Theiss' work, check out UltimateChase.com or Douglas Main's story at OurAmazingPlanet. And if you're a fan of the northern lights or meteor showers, you'll want to click through SpaceWeather.com's photo galleries as well.

Tonight's early reports suggest that this year's Geminid display is shaping up as a great show. If you snap a picture of the meteors  — or the northern lights, for that matter — please consider sharing it with us via NBC News' FirstPerson photo upload page for sky highlights. If I get enough pictures, I'll pass them along on Friday.

Chad Blakley

The aurora season is off to a glorious start, as evidenced by this picture from Sweden's Abisko National Park, taken by photographer/guide Chad Blakley. For more of Blakley's work, check the Lights Over Lapland website and Facebook page.

Summer isn't even over in the Northern Hemisphere, but the season of the northern lights is clearly getting an early start.

Saturday's autumnal equinox marks the traditional start of the aurora season in Arctic regions, and with solar activity building up to the top end of its 11-year cycle, we can expect more than the usual allotment of glow-in-the-dark skies. For some reason, this last week of summer has been particularly active on the sun.

"Another day, another coronal hole high-speed stream," the National Oceanic and Atmospheric Administration's Space Weather Prediction Center reports today on its Facebook page. That means there's a higher chance of interaction between the electrically charged particles of the solar wind and our planet's magnetic field. SpaceWeather.com's Tony Phillips quotes NOAA forecasters as saying that there's a 25 to 30 percent chance of strong polar geomagnetic storms over the next three nights.

If the geomagnetic buffeting gets too strong, that's potentially bad news for electric-grid managers and satellite operators. But a mild elevation in solar activity is a boon for aurora-watchers, and it looks as if we're experiencing the bright side of a solar upswing right now.

Chad Blakley, a photographer and tour guide for Lights Over Lapland at Sweden's Abisko National Park, says the sights have been impressive — and he has the pictures to prove it. 

"Aurora season has been in high gear for nearly a month in Abisko, and it looks as though this year could be something very, very special," he told me in an email. "We are entering the peak of the solar maximum, and if history is any indicator we should see a marked increase in aurora activity. As you can imagine, I am one very happy man."

Ed Stockard sent in a similarly glowing report from Summit Station, a research facility that's 10,530 feet above sea level on the Greenland ice sheet. "The auroras came on fast and furious, moving and dancing across the entire sky," he told SpaceWeather.com. "Aurora season has definitely begun on top of the ice sheet. Bring on the lights!"

Stockard has already been posting some fantastic pictures to his Flickr gallery. In a follow-up email, Stockard told me more about the Summit Station operation, which is sponsored by the National Science Foundation:

"There are five of us here for what we call the first phase of winter. This lasts between mid-August and early November. At that time, another crew of five takes over until sometime in February. A third phase completes our winter phase until mid-April, when an inflated summer crew comes in. The summer season is busy at Summit with researchers mainly from the U.S. but also around the world, doing their NSF-funded research. Most science involves atmospheric research and is tied to the deep ice core drilled here in the 1990s. ..." 

Check out these images from Blakley and Stockard, as well as a time-lapse video captured by Helge Mortensen in Tromsø, Norway. You can expect to see a lot more of this in the months to come.

The auroral display takes on different hues over Sweden's Abisko National Park. The color variations are due to the differences in the composition of the atmosphere at different altitudes. The greenish glow dominates, but the aurora can turn reddish at higher altitudes, as seen here. Check out the Causes of Color website to learn more about auroral colors.

The solar storm that swept past Earth over the weekend didn't disrupt any power grids, but it did turn on the auroral lights for skywatchers over a wide swath of North America, extending at least as far down as Arkansas.

SpaceWeather.com cataloged stunning photos from the usual places in northern climes, including Canadian provinces as well as the northern tier of the United States. But this particular solar storm — sparked by last Thursday's big coronal mass ejection, or CME — didn't stop there. Photographers sent in pictures from Arkansas as well as Ohio, Nebraska, Utah, California and other locales well south of the usual places. There were auroral images as well from Scotland, Hungary, and yes, from New Zealand, Tasmania and the South Pole at the other end of the world.

Observers knew they were in for something big, due to the fact that the flare associated with the solar eruption reached an extreme level of X1.4 on the classification scale for solar outbursts. The radio blast from a sunspot region known as AR 1520 resulted in a strong radio blackout for some high-frequency communication systems, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.

Extreme solar storms have been known to knock out electrical grids as well as satellites, but this one apparently had no ill effects. Today, the prediction center said the stormy space weather "is finally showing signs of weakening."

"No further significant activity has occurred, and while Region 1520 has become less of a threat, it still has the potential for further activity," the center reported.

The sun is heading toward the high point of its 11-year activity cycle, with the maximum expected next year. That means this weekend's storm could just be a foretaste of what's ahead for aurora-watchers and space weather forecasters over the coming months. In the meantime, check out this gallery featuring the latest pictures from the world's greatest light show:

Robert Snache, a photographer living in the Rama First Nation in Ontario, captured this view of the northern lights on the night of July 8-9. For more about Snache and his work, check out Spirithands Photography on Facebook.

A crack in the magnetic field sounds like the start of a sci-fi movie, but it's actually an opportunity for a beautiful auroral light show — as seen in these pictures.

SpaceWeather.com's Tony Phillips says the interplanetary magnetic field near Earth experienced a fluctuation last night and tipped south, opening a crack for electrically charged particles to interact with atoms and ions in the upper atmosphere. "Solar wind poured in and ignited the lights," he wrote.

The result was a five-star performance, staged for skywatchers in northern latitudes. "I had gone out to search for noctilucent clouds, but instead I found a super-clear night with northern lights," photographer Robert Snache of Ontario's Rama First Nation wrote.

Snache told me that he's the guy in the foreground of the picture, which was "shot with a 10-second timer." For more of Snache's work, check out Spirithands Photography on the Web, Facebook or Flickr.

South of the U.S.-Canada border, Shawn Stockman-Malone of Lake Superior Photo also got a great view of the northern lights from Michigan's Upper Peninsula. We've featured Stockman-Malone's time-lapse videos before, but this one is different in at least two respects. First, the pace of the video is slower, which is "more realistic to what you might see with the aurora" in real time, he said. And if you click the video to full-screen resolution, you'll notice a dark shape flitting through the start of the scene. That's a great blue heron, Stockman-Malone said.

"Scared the heck when I saw it flying around just barely over the lake," he told me an email. "All I saw was a big black blob, thought maybe it was a goose. I didn't see it on the shore until I put the lapse together. I must have spooked it when I went walking around looking for other photo angles."

The auroral show could light up northern skies once again tonight: Space weather forecasters say that a strong wave of solar particles, blasted out from a sunspot region on Friday, could deal a glancing blow to Earth's magnetic field overnight. "NOAA forecasters estimate a 25 percent to 30 percent chance of polar geomagnetic storms if and when the cloud arrives," SpaceWeather.com reports.

To keep up with the solar storm prediction, check out the Space Weather Prediction Center's website and Facebook page. As of this writing, we're in the midst of a G1 geomagnetic storm. The prediction center's auroral map provides a rough idea of where the northern and southern lights might be visible, and the Geophysical Institute at the University of Alaska at Fairbanks also offers a great website for aurora-watchers.

Update for 10:06 p.m. ET: This is a great week to see Jupiter and Venus together in the pre-dawn sky, and on July 14-15, the moon joins the morning show. So, even if you're not in the aurora zone, there's still a good reason to stay up late ... or get up early. If you snap a picture of a celestial sight, please consider sharing it with us via msnbc.com's FirstPerson photo-upload webpage.

Brad Goldpaint

Photographer Brad Goldpaint captured this view of the northern lights over Crater Lake, Ore., early Sunday.

A double-burst of solar particles sparked auroral lights over the weekend, as expected — but at least in some parts of the world, the colors were not what you'd expect. Instead of the typical greenish glow, observers reported seeing reds, pinks, violets and even blues.

"It's been many years since I saw the blue in our auroras, but Saturday night they came back," John Welling reported in a note accompanying the photo he posted to SpaceWeather.com.

Pinks, reds and blues also dominated the scene captured on camera early Sunday by Brad Goldpaint, from a vantage point above Oregon's Crater Lake. In an email, Goldpaint told me the opportunity came about "by pure coincidence."

"Capturing this famous light show had been a dream of mine for several years, but I could not have imagined the lights showing up in my own backyard!" Goldpaint wrote. "After setting up near the Rim Village Visitor Center lookout area, I began to notice a faint band of moving light slowly making its way from behind the Watchman Tower, around 1:30 a.m. My camera began picking up bright pink bursts of light towards the north, with what also looked like unfamiliar vertical bands of light stretching upwards from the horizon. I quickly changed my camera’s white balance to confirm I was not picking up some random light pollution, or hallucinating in my drowsy state. Following additional exposures, I came up with the same amazing results. The magical shifting scene continued until sunrise, and like most days in the wilderness, I was awed and humbled by true nature personified."

The photo now graces Brad's portfolio at GoldpaintPhotography.com.

The colors of the aurora depend on the wavelength of the light emitted when fast-moving, electrically charged particles from the sun interact with different types of atoms and ions in Earth's upper atmosphere. If the particles hit mostly oxygen atoms, the light will be in the greenish-yellowish-reddish range. Collisions with nitrogen atoms produce the blue, purple and deep red hues.

The altitude of the auroral glow also affects the color: At altitudes between 60 and 120 miles (100 and 200 kilometers), the oxygen emissions tend toward the green side of the spectrum. At higher altitudes, you'll see more red. Blend all those colors, and you get a beautiful, wide-ranging palette.

The "Causes of Color" website provides a fuller spectrum of information. And speaking of a fuller spectrum, here are more of the weekend's colors, plus a bonus video:

Pink and purple rays highlight this picture of the aurora as seen from South Dakota's Black Hills by Randy Halverson. Technical details: Canon 5D Mark III, Canon 24-70, f/2.8 ISO 3200, 20-second exposure. For more of Halverson's images, click on over to Dakotalapse.com.

Stephen Voss

Stephen Voss snapped pictures of the southern lights from a spot near Invercargill in the south of New Zealand. "A dull arc hung around for a couple of hours before suddenly exploding with a mixture of rays and curtains," Voss told SpaceWeather.com. Check out Voss' gallery at Deep South Astrophotography.

Scott Lowther

Scott Lowther snapped this panoramic picture of Saturday night's auroral display as seen from Tremonton, Utah. The shot was taken with a Nikon D5000 and a 55mm lens at f/1.4 with 6-second exposures. For more of Lowther's photos, check out the Art by Earthlings website.

Shawn Malone / LakeSuperiorPhoto.com

Shawn Malone snapped this picture before dawn on Sunday morning from Marquette, Mich. "Got to witness the tail end of aurora activity as the skies cleared about 15-20 minutes before the sunrise light moved in," Malone told SpaceWeather.com. "Photos taken between 3:50 a.m. and 4:15 a.m. Bright aurora, with rays of light overhead, almost forming a corona. Beautiful purples came through on the exposures, but only light visible to the eye, as is typical with auroras right before sunrise." Check out LakeSuperiorPhoto.com for more of Malone's work.

Skywatchers as far south as Colorado and Kansas witnessed a quick flare-up of the northern lights this week, which called to mind the brilliant, beautiful displays that northerners saw earlier this year. The skies have settled down — for now — but developments on the sun suggest we could be in for another wave of auroral glories.

The greenish glow over Lake Superior, recorded from Michigan's Upper Peninsula at 2 o'clock in the morning by Shawn Malone of LakeSuperiorPhoto.com, was impressive enough to make NBC's "Nightly News" on Tuesday night. In an email, Malone told me that the "intensity caught me off guard."

"Check out the passing freighter for scale," Malone said in his comments on the Vimeo version of the video. "What a view those sailors must have had!"

Mark Riutta had a similar view from Copper Harbor Cabins on the Upper Peninsula, as the time-lapse video below illustrates. Riutta told me over the phone that he and his girlfriend were getting the cabins ready for the summer season and were surprised by how bright Tuesday's display turned out to be. "We were just about to go to sleep, when we looked out and wondered, 'Why is it so light out there?' he said.

SpaceWeather.com provides a roundup of auroral images from a dozen U.S. states, mostly in the Midwest but also including the top state for the northern lights, Alaska. And speaking of Alaska, here's an unconventional view of the aurora that was recorded from a height of 90,000 feet during "Project Aether: Aurora," a scientific experiment that took place this month:

Project Aether, led by University of Houston physicist Ben Longmier, sent up almost two dozen weather balloons laden with high-definition cameras and scientific instruments to monitor auroral activity near Fairbanks. Most of the payloads have been recovered, but the student researchers are still on the lookout for a few that haven't yet been located. If you happen to be in the Fairbanks area and find one of them, you could win a prize.

More prizes could be in store for aurora-watchers: The National Oceanic and Atmospheric Administration's Space Weather Prediction Center reports that we're currently in the midst of a minor geomagnetic storm, which could spark another wave of northern lights. What's more, an active region of the sun known as AR1465 has developed the type of magnetic field that's associated with stronger X-class outbursts.
