Mike Hill's SID report sums up the amount of activity for this part of the cycle. However, on the rare occasion that the sky has cleared, I've taken out the PST and always find a few prominences to observe. Gema Araujo continues to capture a wealth of imagery. The top H-alpha image on Feb 6, 11:05UT, lower left Feb 11, 11:14UT and right on Feb 1, 11:13UT. You can track Gema's images at http://www.astrosurf.com/obsolar/ I'd also like to thank Ernest Richardson for submitting his images of prominences. I'll try and find a scanner to include them next month.

Solar Events

There were no SID events in February. None! Not one correlated SID event and not even one GOES X-Ray flare recorded. A very very inactive sun is upon us. I'm sure many of you long time observers are searching your memories for a time like this in the past. Is this normal for minimum or is this an anomaly? I for one cannot remember in the past 35 years of solar observing seeing so little activity. It really makes me wonder what is going on under the surface of the sun that we are not seeing. So in an odd way this absolute lack of activity is quite compelling. Keep looking and monitoring because it's sometimes what you don't see that can be the most interesting. As always I have included the list of observers who reported this month in the official report submitted to the AAVSO and on file on the web site. Thanks again for your contributions and keep those monitors running. The next big flare might be just around the limb.
