GOES 15 is working again as of 16:00 UTC today. Just a few hours into the Xray monitor being back in business, we have a "registered" M1.0 flare peaking at 19:40 UTC. This solar flare came from old sunspot region 1431 as it rotates back into a earth facing direction in the far southeast limb.
2012-03-23 16:50 UTC SWPC GOES Data Again Available- Just in: GOES 15 xray, particle and magnetometer data are now again accessible as of about 1600 UTC (noon EDT) today. Imagery should be available again at approximately 1900 UTC.
It's anyones guess on how many larger flares we have missed while the monitor was down.
