| 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 a moderately active month for SID activity. There were 39 correlated SID events to report, most of medium to low importance rating. The GOES-12 spacecraft recorded 210 X-Ray flares and of these only 4 were M-Class events with all the rest of lower intensity. The activity was spread fairly evenly throughout the month with a slightly larger amount of activity at the beginning.
