I was at Sierra la Rana last night SW of Alpine, TX (30 21 15.8 N, 103 33 55.5 W, 5165 ft.) photographing the Milky Way with a digital SLR on a camera tracker, and started a 5-minute exposure of the Scorpius region around 10:47 p.m. CDT (2010-08-02 0347 UT). The photograph shows a circular reddish cloud located in Norma at about 15h 43m -48d 46' (2000) that was not visible to the unaided eye. There is no nebula at this location, nor does this appear to be a "ghost" image in the optics, so I suspect this is a rocket plume from some rocket firing in Earth orbit. Here's the full-resolution image for your review. http://skythisweek.info/SLR201008020347_1543-4846.jpg You will find the "nebula" in the lower right portion of the image. Are any of you aware of a rocket firing on orbit a few minutes before 2010-08-02 0347 UT? Thanks much, David Oesper Alpine, TX USA -------------- next part -------------- An HTML attachment was scrubbed...
