    NOTES:
    --------
    (1) Herewith positions of the CENTAUR rocket and OTV-3 as observed
        last night. I did not measure all the images but tried to get
        a good spread.
    
    (2) The CENTAUR is academic as it has now been de-orbited but what
        is interesting is that the video footage clearly shows both the
        CENTAUR and OTV-3 doing retro-burns.  The CENTAUR was about a
        magnitude fainter than OTV3 which was about mag +3.5~+4 -steady.
    
    (3) I plan to observe again tonight as conditions currently look
        good.
    
    (4) I still have a few more satellites to process, including
        USA 129 and one of the ELISA objects.
    
    Cheers
    Greg
