    There is no object on my May 3 images at the predicted position of 03-018A (Gsat 
    2), so Ted could very well be correct (always difficult to tell if absence is 
    real, as it can also be that an object is beyond my detection limit. Eutelsat 
    W48 is clearly visible just northeast of the position though on my images, and 
    so is Syracuse 3A to the west of it).
    
    I hope the other UNID can be recovered as well (Greg?). I have a feeling that 
    particular one is probably PAN (09-047A) relocating: if someone (Greg?) could 
    check the original PAN position and confirm it is no longer there near Yamal 
    202, as well as trying to recover that UNID, that would be very welcome.
    
    Sky has thick cirrus here now, so I'll probably be out of the game this evening.
