    Hi all,
    
    On my images of yesterday, is a bright near-geostationary object that I cannot 
    100% identify with a known object. The only possible candidate I can find would 
    be Mercury 2 (96-026A, 23855) but then it would be off in position:
    
    00000 00 000X   4353 G 20120618223432250 17 75 1747298-168680 56
    00000 00 000X   4353 G 20120618224332250 17 75 1757194-169560 56
    
    
    Very approximate orbit using Scott's software:
    
    1 00000U 00000X   12170.94690104 0.00000073  00000-0  50000-4 0    06
    2 00000   8.7402   9.8836 0000122  49.9816 208.0128  1.07206948    07
    
    Mercury 2 (from inttles file)
    1 23855U 96026A   12170.23476887  .00000000  00000-0  00000-0 0    05
    2 23855   8.8849  11.6188 0523724 204.3995 153.0540  1.00306992   392
    
    
    Note: This is with my new camera (Canon EOS 60D - my old 450D died on me in te 
    second half of May, with shutter failure) and I am still in the process of 
    calibrating the timing of this camera. I have used some preliminary calibration 
    results but times still can be off a bit (but by no more than 0.1s I suggest). 
    For geostationary objects, this potential error does not matter much, I believe.
