**** MAJOR SOLAR FLARE ****

A major solar flare occurred today, August 27, at 7:07 a.m. MDT (1307 UT). This activity originated from a large active region complex currently positioned near the center of the solar disk. This event was the largest of a number of sizeable x-ray flares from this area in the past 24 hours.

This group continues to grow and change, and more substantial x-ray flare activity is likely. In addition, a significant mass ejection may occur from this site, and, if it erupts, could cause a geomagnetic storm at some point during the next week.

Solar flares are known to affect communications and navigation systems operating on the dayside of the Earth. Electrical power grids and satellite operations can be impacted during large geomagnetic storms.

mabel, any idea which direction they're headed in? thankfully, the last big CME went away from us, instead of toward. too bad it didn't happen during the eclipse; would've meant really cool pictures.

Here is where you can get the daily info on solar flares.

I've been watching this off and on for about a year. X-class flares are larger than the M-class. There have been lots of both during the last year. The site gives a prediction for isolated X-class flares during the next 3 days.
