The wonderful H-alpha image was taken by Javier Ruiz from Observatorio Astronomico de Cantabria, Spain on March 13, 2009 at 14:55UT. He used a Coronado SM90 on a TSA102 with a DMK41 camera.

Thanks again to all the dedicated observers who continue to patrol the sun and submit reports. Your data still counts and reflects the current status of this cycle. Don't forget to submit your images, drawings and SID plots to include in the bulletin.

The events listed above meet at least one of the following criteria

Event reported by two or more observers within +/- 5 minutes
Event matched to GOES-8 XRA event to within +/- 15 minutes and event time < 1000 UT
Reported by observer with a high quality rating > 8 (scale 1-10)

Solar Events

March was another slow month with 0 correlated SID events. There was only a single X-Ray flare detected by the GOES-12 spacecraft and that was only a B Class event. On the upside we continue to have a fair amount of observers reporting in on a regular basis so at least you all haven't lost interest yet.
