Solar Events

November started out as a bit of a carry over from the very active month of September. There was a lot of activity throughout the month but the most powerful events were at the beginning. The GOES-12 Spacecraft detected 190 X-Ray flares. Of these 24 were M-Class and 4 of them were X-Class. All of the X-Class events occurred in the first four days of the month. Observers reported a total of 69 correlated SID events. Most of these were pretty evenly spread across the importance rating of 1 to 2+ with only a few long duration events reported. Thanks to all of you who contributed. I hope you all have a Merry Christmas and Happy New Year.

I am happy to say that NAA in Cutler, Maine is finally back on the air after a very long maintenance period that lasted all summer and most of this fall. I hope they got all they had to get done completed. All of us that rely on NAA as our SID detection siganl base are, I am sure, quite disappointed to have missed out watching all the action of the last couple months when the sun burst forth with a flurry of activity. But we seem to be back in business now. So to those of you who have your rigs shut off, its time to fire them back up and start monitoring once again.
