Solar Storm, Auroras This Weekend: 3 Things To Know

A​ solar storm is likely to yield a brilliant celestial show for millions in the Northern Hemisphere this weekend – even in some places that don't often see the aurora borealis, or northern lights.

H​ere are three things you'll want to know about this special event that's expected to peak over the weekend:

1​. An unusually strong geomagnetic storm is ongoing: This is the first time that an Extreme (G5) Geomagnetic Storm Watch has been issued by NOAA's Space Weather Prediction Center since October 2003. In their warning, the agency said Earth-directed coronal mass ejections are expected to continue all weekend.

2​. The northern lights could be visible as far south as Alabama: This is obviously not your ordinary geomagnetic storm, so the viewing area could be extraordinary, too. Experts say the viewing area could extend all the way down into the Deep South, with parts of northern Alabama potentially being able to see some of the show. In the West, areas as far south as Northern California might also see some of the auroras.

3​. Weather conditions could cooperate for viewing, especially in parts of the country that don't traditionally see the northern lights. While parts of the Northeast and Great Lakes are likely to be cloudy and rainy for part of the prime viewing window over the weekend, clearer skies are expected along the West Coast. Parts of the South, as well as the Central and Northern Plains, could have clearer skies Friday night, but clouds might become more numerous Saturday night.

A​nd here's a bonus tip: Even if you're in an area where clouds shroud the overnight viewing, did you hold on to those eclipse viewing glasses you bought in early April? If so, find a time when the skies are clear, throw on those glasses and take a peek at the sun. This geomagnetic storm is so big, it may be visible to the naked (but protected!) eye.
