2026-02-02X-8.1 CLASS FLARE

Posted on 2026-02-02 by Librarian

Hefty X-8.1 Class Flare yesterday evening. Caused some radio blackouts in South America and the Southern Atlantic. There has been a bunch of CME ejections but NOAA is still not sure where they’re headed. Might be toward Earth but still unknown.

An X8 is not really strong enough to do any significant damage. Could possibly trip a few grid breakers if it hits Earth squarely but even that is just a possibility.

Still this one huge sunspot threw off 20+ M Class Flares and 4 X Class Flares yesterday. It’s almost guaranteed to keep showing off today. Since it’s just starting to swing across the face of the Sun to face us it bears watching. I suggest checking spaceweather.com periodically during the day to see what it’s going to produce today (Monday).
