Professor Emeritus of Physics and Geophysical Institute Aurora Forecaster Charles Deehr issued an Auroral Alert on March 13, 2012. The notice came after a significant solar event occurred the same day. According to the National Aeronautics and Space Administration, the sun erupted with an M7.9-class flare that peaked at 1:41 p.m. EDT. The flare was from the same active region that has produced flares and coronal mass ejections all week. The region will soon rotate out of Earth's view, but until then, active aurora is in store for viewers.
In Alaska, the effects from this recent solar event could occur as early as 2 a.m. AKDT on the morning of March 15. The best auroras should occur in the night/early morning of March 16/17, but aurora should be visible until the morning of March 18.
