Auroras in the USA

Last night, Northern Lights spilled across the Canadian border into more than a dozen US states, turning the sky purple and green as far south as Colorado and Nebraska. Subscribers to the Space Weather Alert System (text, voice) knew the storm was coming, but others were surprised:

“Last night, I drove to Crater Lake National Park to photograph the Milky Way rising above the rim,” reports Oregon photographer Brad Goldpaint. “I was staring upward towards a clear night sky when suddenly, without much warning, the aurora borealis began erupting in front of me.”

“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 continues. “The moon rose around 2am and blanketed the surrounding landscape with a faint glow, adding depth and texture to the shot.”
