A surprisingly strong geomagnetic storm swept over our planet this weekend, resulting in a surprisingly strong set of videos showing the northern lights (and the southern lights, too).
A couple of the videos pack in some extra goodies. For example, Oregon photographer Brad Goldpaint's video of the aurora over Crater Lake features a long-exposure streak left behind by the International Space Station as it passed overhead on Saturday morning.
"Like the aurora, the ISS was another great surprise during the night," Goldpaint, who offers a treasure trove of night-sky views on his website, told NBC News in an email. "Usually I pay close attention to events like these, but this night completely threw me off with strong aurora levels and the ISS flyover."
Goldpaint told SpaceWeather.com that he drove out to Crater Lake National Park on Friday night primarily to photograph the Milky Way, not thinking that there'd be any fireworks. "I've waited months for the roads to open and spring storms to pass, so I could spend a solitude night with the stars," he explained. But by around 11 p.m., he was picking up on the signs of a great auroral show in the making.
"With adrenaline pumping, I raced to the edge of the caldera, set up a time-lapse sequence, and watched northern lights dance until sunrise," he wrote. "The moon rose around 2 a.m. and blanketed the surrounding landscape with a faint glow, adding depth and texture to the shot."
Scientists aren't exactly sure what caused the upswing in geomagnetic activity. "Current speculation focuses on a co-rotating interaction region (CIR) — that is, a shock-like transition zone between high- and low-speed solar wind streams," SpaceWeather.com's Tony Phillips reported.
There's a chance that observers in higher latitudes will see enhanced auroras on Sunday night as well, due to the interaction between a high-speed solar wind stream and Earth's magnetic field. To keep up with the aurora forecast, check in with the National Oceanic and Atmospheric Administration's Space Weather Prediction Center and its automated Ovation prediction page. If you're in the zone, the best time to see the aurora is after midnight. In the meantime, check out these aurora time-lapse videos on Vimeo.
