Update on the UNID geostationary: Greg observed it too!
On the evening of December 8, while imageing PAN, I captured an unknown object, apparently in a geostationary orbit, close to the commercial geostationary objects Turksat 2A and Turksat 3A. See my earlier report and pictures here.
Since then, I have been completely clouded out. However, Greg Roberts in South Africa had clear skies yesterday, and managed to recover the object. It has moved closer to the Turksat duo.
Greg is in some doubt whether this really is the "lost" SCS 3-11 (2000-001A ) as he feels it is too bright.
To be continued!!!!!

Senegalese skies
I spent the first half of this month in Africa, in Senegal, where I took part in the 2010 PANAF/Safa conference (PANAF = Pan-African Archaeology Conference) in Dakar. After the conference my girlfriend, two friends/colleagues and me added a few days of tourism through the country.
During the conference field excursion to the Saloum delta, and later during our private trip to the Lompoul sand dunes, I took a few shots of the Senegalese night sky. I didn't have my regular astrophoto lenses with me, so used my Tamron 2.8/17-50 mm zoom (not an ideal choice for astrophotography) at 17mm. The camera was fixed on a tripod, no guiding, exposure times ranged between 10 and 20 seconds, ISO 1600.
Below are some of the resulting pictures, plus a photograph of me taken at a megalithic site during the conference field excursion.

Another Keyhole flare
Although the skies were somewhat hazy, observations were conducted on the evenings of April 15th and 16th. Targets were the various IGS objects (1B, 5A, 5r/b), the Lacrosse 5 r/b, and the KH-12 Keyholes USA 129 and USA 186.
USA 186 was so friendly as to flare in my camera image on the 16th. The flare occurred at 20:43:40.75 UTC (Apr 16). Below is the image, and the resulting profile (with saturation at the peak). The two bright stars are the front stars of the pan of the Big Dipper, alpha and beta Uma.
