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 / Spirithands Photography

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.

Laurent Lamy

These composite images show Uranian auroras as bright spots on the planet's disk on Nov 16, 2011 (left), and on Nov. 29 (right). The images from the Hubble Space Telescope have been processed to bring out details in Uranus' faint ring system.

Thanks to the Hubble Space Telescope, astronomers have caught a rare display of auroras on Uranus, which ranks among the solar system's oddest planets.

Unlike the beautiful, rippling curtains of greenish light we've been seeing in earthly skies over the past few months, the Uranian auroras are short-lived bright spots sitting on top of the ice giant's bluish cloud tops. But they're caused by a similar mechanism, involving the interaction of electrically charged particles with atoms and ions in the planet's upper atmosphere.

NASA's Voyager 2 probe picked up the first evidence of Uranus' auroras in 1986. "Since then, we've had no opportunities to get new observations of this very unusual magnetosphere," Laurent Lamy, an astronomer at the Observatoire de Paris, said today in a news release. There have been a few hints of auroral observations, but Hubble's views from last November rank as the best views yet. Lamy and his colleagues provide the details in a paper published by Geophysical Research Letters.

The team took advantage of a lucky break and a favorable planetary alignment: Last year, Earth, Jupiter and Uranus were lined up so that energetic solar emissions could flow past each planet in turn. When the sun produced several outbursts in September, the astronomers timed the flow of the particle storm past Earth a couple of days later, and then detected the flow past Jupiter two weeks after that. On the basis of those readings, they calculated that the outburst would reach Uranus in mid-November, and scrambled to schedule observing time on the Hubble Space Telescope.

Uranus is an oddity because it basically rotates on its side as it orbits the sun. The orientation of its magnetosphere is tilted 60 degrees with respect to its rotational axis. As a result, during the current season, each of the planet's magnetic poles turns to face the sun in the course of a Uranian day. "This configuration is unique in the solar system," Lamy said.

Hubble was well-placed to catch the auroral flashes on the sunlit side, near Uranus' north magnetic pole. Each flash appeared to last only a couple of minutes, the astronomers said.

These new findings solidify Uranus' place on the list of planets flashing with auroral lights. Jupiter and Saturn are also on the list. Mars is thought to be capable of localized auroral effects, even though it doesn't have a global magnetic field. (In fact, some observers suspect we saw evidence of those effects last month.) Earlier this month, astronomers reported seeing auroral-type activity on Venus as well.

Lights on Earth
And then there's Earth. Last October, a solar outburst sparked northern lights that could be seen as far south as the state of Mississippi, and over the past month, higher-latitude residents have been treated to almost as many fireworks displays as Disneyland tourists typically get to see. Although the approach of summer is starting to cut down on the opportunities to see auroras in the Northern Hemisphere, some folks got great views as recently as last night. Here are a few of the highlights:

Shawn Malone of Marquette, Mich., snapped pictures of the aurora from the shores of Lake Superior. "The sky was ablaze in light," Malone told SpaceWeather.com. "Northern lights were so bright they lit up the beach!" For more from Malone, check out LakeSuperiorPhoto.com and his Vimeo video gallery.

Here's a different angle on the aurora and the International Space Station, captured by Brian Larmay of Beecher, Wis. The long streak in this time-lapse photograph is the space station, sailing across the sky. To see more of Larmay's pictures, check out his SmugMug gallery.

'Where in the Cosmos'
Today's picture of auroral displays on Uranus served as this week's "Where in the Cosmos" picture puzzle on the Cosmic Log Facebook page. It took only a couple of minutes for Shirley Beningo to blurt out which celestial body was shown in the picture, and what the bright spots were. To reward her for her quick cosmic vision, I'm sending her a pair of cardboard 3-D glasses, wrapped up in a 3-D picture of yours truly. Ashley Nicole and Gerry Marien came in as the runners-up, and are eligible for 3-D glasses as well.

Thorbjørn Haagensen

Thorbjørn Haagensen took this picture of the northern lights on April 3 from Hillesøy, close to Tromsø in northern Norway.

A stunning aurora season is finally coming to an end in the far north, thanks to the longer days and the shorter nights. But there were still a few opportunities this week for the northern lights to ripple across the sky in a "last dance," as this picture from Norwegian photographer Thorbjørn Riise Haagensen shows.

"Beginning in the middle of May, the midnight sun brings sunshine all night long," Haagensen told SpaceWeather.com today. "Already some daylight is visible at the horizon at midnight. There is still enough darkness, though, for the last dance of the auroras."

Haagensen's photograph shows the aurora's glow in northern Norway; click on over to his Haagensenfoto.no website for more of his pictures, including an aurora gallery. Speaking of galleries, SpaceWeather.com offers some thrilling pictures from Minnesota and northern Quebec as well as Norway.

Here's a time-lapse movie of the northern lights' last dance that was captured by Jan R. Olsen, a photographer who lives in Olderdalen, Norway. "Not many days left with the aurora," he wrote. "This was shot on the night of April 2nd. Soon it will be too light in the night to see the aurora."

Even though the northern lights may be on the wane, the southern lights should be hitting their prime — and the people in the best position to see the show in the south are the astronauts on the International Space Station. Keep an eye on the Gateway to Astronaut Photography of Earth for shots of the aurora australis from space.

The aurora's glow makes for thrilling photographs, but let's face it: The shimmer of the northern lights is a big part of the appeal. Here are three time-lapse video views looking at the northern lights from above and below, plus still-photo highlights from the past day or two.

The International Space Station's view of the green and red aurora was recorded back on Jan. 22, but the clip is part of a batch of seven night-flight videos released on Thursday via the Gateway to Astronaut Photography of Earth. The shots were snapped as the station soared from the Pacific Ocean, west of San Francisco, northeast across the United States toward Saskatchewan in Canada. The camera is looking northward, and to my mind, the presence of the station's solar panels and robotic arm in the foreground is a plus, not a minus. For a sharper version, go directly to the high-resolution QuickTime video.

The aurora most commonly takes on a greenish hue, but when electrically charged particles from the sun interact with atomic oxygen at higher altitudes — say, up to 200 miles — the glow turns red.

The past week has been a godsend for aurora-watchers, thanks to a series of outbursts from an active region on the sun, but now the solar storms have settled down. Observers caught the tail end of the heightened activity on Thursday night in regions of Scandinavia, Iceland, Scotland, Greenland and North America, as well as Australia, New Zealand and Antarctica in the south. Check SpaceWeather.com as well as the National Oceanic and Atmospheric Administration's Space Weather Prediction Center for updates. And check out this album of videos and photos from all over:

Iurie Belegurschi

Iceland's Iurie Belegurschi offers this stunning picture of the aurora with the Venus-Jupiter conjunction shining in the sky, off to the right. For more of Belegurschi's photography, check out his Facebook page.

Andrei Penescu

Andrei Penescu captured this view of the northern lights on March 15 from Kangerlussuaq, Greenland. "Tonight was very special because it was the first time I've seen the sky full of red auroras. ... It was the best aurora show I've ever seen!" Penescu told SpaceWeather.com. Check out the gallery at SpaceWeather.com.

ESA / NASA

A picture from the International Space Station, provided Saturday by Dutch astronaut Andre Kuipers, shows southern lights between Antarctica and Australia.

Most of the fantastic auroral views we've been getting over the past month have been from the north side of the world — but the southern lights are getting their day in the sun as well, thanks largely to the International Space Station.

The northern lights are more widely seen primarily because the high northern latitudes are more populated than similar latitudes in the south: The southernmost cities in Australia and New Zealand are in the 40s, latitude-wise, while Argentina and Chile dip down into the mid-50s. In comparison, the prime aurora-viewing areas in the north are in the 60s and 70s.

The International Space Station flies as far as 51.6 north and south latitude on every orbit, and its astronauts have a far more commanding view of the polar regions than earthly skywatchers. So it's no surprise that they're regularly seeing the auroral glow during the current period of heightened solar activity. Right now, the station's crew is in the midst of a viewing campaign that's being coordinated with the Canadian Space Agency's AuroraMAX project. Some of the reddish glows reach all the way up to the space station's level, 240 miles above Earth.

"We can actually fly into the auroras," space station resident Don Pettit said recently. "It's like being shrunk down and put inside of a neon sign."

You've got lots of choices for browsing through auroral sights and other views from space. There's Kuipers' Flickr gallery, the NASA 2Explore Flickr site, NASA's Gateway to Astronaut Photography of Earth, the Expedition 30 gallery on NASA's Human Spaceflight website, and the Fragile Oasis Facebook page, where astronaut Ron Garan and his colleagues keep track of everything that's out there. To find out when you can see the space station from your locale, consult NASA's database for sighting opportunities.

This March 6 photo from the International Space Station highlights daybreak on the left side of the horizon, and the southern lights on the right side. The station was flying over the Indian Ocean at the time, or about 1,200 miles south of Australia. The view is toward the east. A Russian Soyuz spacecraft is connected to the Pirs docking compartment at center, and a Russian Progress cargo craft is docked at right.

The space station's astronauts aren't the only ones who are seeing the southern lights: Check out the pictures from New Zealand and Tasmania that are being posted to SpaceWeather.com. And stay tuned: Thanks to a series of solar outbursts over the weekend, heightened geomagnetic activity should continue through Tuesday, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center. That means there could be still more neon lights in the sky. Check out NOAA's Ovation Auroral Forecast and the University's Aurora Forecast website to find out if you're in the potential aurora zone.

Update for 9:30 p.m. ET: Tonight's northern lights were not to be missed at Sweden's Abisko National Park. "Tonight was very special," photographer Chad Blakley of Lights Over Lapland wrote in an email. "We had incredible auroras and were able to watch them dance as Venus and Jupiter went down behind the mountains." Here's a must-see time-lapse video of the scene:

Update for 4:30 p.m. ET March 14: ... And looking back Down Under, here's a wonderful video clip from Ian Stewart in Tasmania, looking south over Bruny Island. "This aurora was short lived, and obscured for the most part by cloud," Stewart wrote. "The cloud cleared just as the sky started glowing an eerie soft red, and the aurora faded into the beams of the rising moon at the end." Still more solar particles are coming our way, so stay tuned for more great views from the north and south. Check SpaceWeather.com for the latest.

Northen lights ripple through the skies over Abisko in Swedish Lapland late March 7.

So far, the disruption caused by this week's solar storm seems to be minimal, but skywatchers are maximizing the opportunity to see auroral fireworks — and tonight just might be prime time for the show. Or maybe not.

For several days now, the sun has been sending out bursts of electrically charged particles, known as coronal mass ejections or CMEs. The most spectacular flare-up came late Tuesday, when two X-class solar flares blazed up from a particularly active sunspot region. The waves of particles associated with those flares began sweeping over Earth's magnetic field today.

Usually, that would suggest that tonight's the night to look for the northern lights in somewhat less northern regions of the globe — say, Massachusetts, Nebraska or Oregon. Two factors could put a damper on those expectations: First, the geomagnetic component of the storm is not as powerful as space weather forecasters had expected, at least not yet. Second, the full moon's glare might wash out the delicate glow of the aurora.

To find out whether there's a chance of seeing the northern lights, check out the Ovation Auroral Forecast map from the National Oceanic and Atmospheric Administration's Space Weather Prediction Testbed, as well as the Aurora Forecast website maintained by the University of Alaska's Geophysical Institute. Right now the outlook is great for Fairbanks and Edmonton, not so good for Boise or Boston. But you never know — and besides, it's worth going out to take a look at the moon and several planets together in the sky, even if the northern lights aren't shining in your locale.

Rest assured the lights will be shining in the usual places, including Scandinavia, Russia and Canada. Here are a few of the beauties from last night. For even more, click on over to the galleries at SpaceWeather.com:

Timo Veijalainen / AV-Lappi

Timo Veijalainen of Sodankyla, Finland, sends along this picture of the northern lights. "There were lots of clouds during the night, but driving to east was answer to our problem," he said in a note to SpaceWeather.com. "Near midnight, auroras started to dance. It didn't last long, but luckily I got few images." Check out the gallery at SpaceWeather.com, and stop by Veijalainen's AV-Lappi website.

AuroraMAX / CSA

The AuroraMAX all-sky camera near Yellowknife in Canada's Northwest Territories captured this subtle display of greenish and reddish auroral lights early this morning. For more from AuroraMAX, check out the project's website and Twitpic gallery.
