‘Cannibal’ Geomagnetic Storm Could Make Aurora Borealis Visible in 10 States Tonight

Here is where and when

Here’s some good news coming off a long holiday weekend as we head into the fall: If you missed the northern lights (or aurora borealis) last night, you may get another chance to catch a glimpse tonight, Tuesday, September 2, and early Wednesday morning, September 3, in some 10 U.S. states.

That’s on account of a powerful “cannibal” solar storm that hit Earth's magnetic field on Monday from 1 million miles away, lighting up skies across North America and Europe overnight.

The aurora borealis is the result of a geomagnetic storm that occurs when a coronal mass ejection (CME), an eruption of solar material, reaches Earth and causes swaths of purple, blue and green in the night sky. This year's increased solar activity (and thus, more frequent northern lights activity) is likely the result of an 11-year sun cycle peaking now through next month.
