    NOTES:
    --------
    (1) Purpose of observing session was a plane scan for X37B. First good
        night for quite a few days - pretty frustrating!
    
    (2) Times only accurate to perhaps 0.2 seconds. The oscilloscope I use
        for setting my time system from GPS signal failed so had to do it
        audibly/manually but time believed possibly good to 0.1 second.
    
    (3) CoSaTrak failed during last minutes of the 107 minute plane scan.
        Steel pin in the elevation gearbox gear sheared so lost elevation
        drive.
    
    Cheers
    Greg
