August came and went, but fortunately there was some solar activity worth observing. Mike Hill welcomes two new SID observers, both from France in his SID section and as always I'd like to thank solar group members that took the time to send in some solar images as well as a little about themselves. This month I'd like to highlight the observations of several European observers.

Gema Araujo, lives in the south of Spain and takes daily images and drawings of the sun using an 80mm f/11 refractor. She became interested in the sun while witnessing the August 1999 eclipse and began regular observations in 2000. The photo and drawing were both made on August 17, 2006 at her home. http://astrosurf.com/obsolar

Roberto Battaiola (A96) lives close to Milan and has been monitoring SID flares since 1999. This plot from August 21, 2006 shows multiple flares while monitoring station HWU at 18.3 kHz. He uses a Gyrator II from fellow SID observer Guglielmo Di Filippo (A93).

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)

I would like to welcome two new observers, both from France. Lionel Loudet (A118) and Jean-Pierre Godet (A119). Both have very impressive setups and get very good clean signals of the stations that they monitor. Lionel also has a very nice SID Monitoring web site which can be viewed by going to the url: http://sidstation.lionelloudet.homedns.org

Sadly, one member has decided to "hang up his loops" as he said himself. Jerry Winkler (A50) will no longer be reporting and his contribution will certainly be missed. Thanks so much Jerry for your many years of dedicated service to the AAVSO SID Program.
