The above plot is from my SID receiver on June 1. Several observers were able to capture these M-class events.
Gema Araujo's solar image on June 5, 2007 at 08:45UT of AR 10960. The M-class flares recorded above came from this group when it was still on the solar limb. It developed into a great active region as it came around the disk as seen in this photograph.
Remember to send me any solar drawings, SID flares or photos for me to include here. There's one person who's been sending in solar photos, but unfortunately there's no name or contact info, so please let me know who you are so I can give due credit in the images.

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)
June was really quite an active month for SID Monitoring. There were 23 Correlated SID events reported by observers and most of these were of medium importance rating. For the first time in many months I have a GOES-12 summary graph (below) that has a scale that goes beyond 20! Month to month I keep it at twenty as a minimum so that one can judge the activity level with just a glance. I increment in blocks of five as needed. June 4th was the most active of the days and was part of a week long surge of activity that lasted just beyond the first week of the month. By the numbers, there were 136 X-Ray flares recorded by the GOES 12 satellite. Of these, 17 were C Class and 9 were M Class. Although most of the month following the early burst of activity was very quiet, activity levels did begin to pick up again at the end.
