Remember to send me any solar drawings, SID flares or photos for me to include here.

Happy Holidays to all our observers and wishing you clear skies for 2008

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

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

Solar Events

November was just as active as October. In other words - NO correlated SID events! In fact the month was so similar to last month that there was once again only one event recorded by the GOES-12 satellite; A minor B-Class event. Indeed, a very in-active sun. Just winding up for the next cycle? Perhaps. We have been in a fairly long period of inactivity, which I myself thought would have passed by now. But it has lasted quite some time and there are now signs that the trend may start to work the other way. Only time will tell and of course the numbers - our numbers. So keep observing, keep up the reports. They are all important. We are down to 11 observers this month out of the usual 18-19 so we do have a few observers taking a break from the monitoring for a while. I'm sure the number of observers will pick up once the next solar cycle - cycle 24 - begins.
