Observations 09 DEC 2010 ------------------------------------ CoSatrak system. CCD setup: Meade DSI Pro II Monochrome CCD camera without filters. using integration times of 5 sec min to 25 seconds maximum depending on brightness of sky in particular area.No image processing done, but some done automatically in the auto reduction software. Used with 4 inch SKYWATCHER refractor- model 1025 - fitted with home made focal reducer to give an f/2.56 system. Image scale is 6.56 arc sec/pixel and field of view 84.8 x 63.2 arc minutes. Shows 15th magnitude stars in real time with reasonably good conditions. Exposure time to nearest second inserted into image FITS header from PC clock which is automatically checked every minute against GPS signal. Processed automatically with APEX VIDEO setup: 145mm f/2.5 telephoto lens with MINTRON video surveillance camera with frame GPS time stamping. Processed manually.

However the object was now very close to TURKSAT 3A and TURKSAT 2A.The SPACETRACK elements are not good enough to be able to say what the three objects are but I have attempted to group the three objects. Two more or less maintained station relative to one another and since the Turksat satellites have inclination very close to zero degrees I have tentatively identified which is which. The third object appears to be moving, so has a higher inclination. For the first group of exposures it appeared on one side of the TURKSAT group and in the second exposure group it was on the opposite side so it would appear that sometime between the two exposure groups, seperated by about 2 hours, it passed through the two Turksat satellites. Im not 100% convinced that the object identified as DSCS 3-11 is correct as its brighter than what I am accustomed to seeing DSCS satellites, BUT I am more often wrong than right when I dont know what Im talking about so I could be mistaken. (2) Had a good search for MENTOR 5 low on eastern horizon but nothing seen so maybe its not coming my way...
