MAINE, USA — Those who didn't get the chance to view the rare appearance of northern lights over Maine on Friday got a second chance to take in the awe-inspiring event Saturday night.
The northern lights, aurora borealis, is a natural light display caused by solar wind. It's typically visible in high-latitude regions of the world, like Antarctica, but this weekend, Maine was in luck.
Brilliant hues of purples, pinks, and greens swept across the night sky for the second night in a row due to a massive solar storm.
NOAA said G3 (strong) and G4 (severe) storm conditions persisted through most of the day on Saturday, with a G5 (severe) period early in the day. A watch for G4 or greater conditions is expected to persist throughout Sunday, and aurora borealis viewing may still be possible in some parts of the U.S. Sunday night.
Viewers sent NEWS CENTER Maine photos and videos of the northern lights this weekend. Check them out below.
