    Notes:
    -------
    
    (1) Cloud obscured the higher elevation of shadow exir at about 35 degrees
        elevation heading south, so went to a point clear of cloud and got this
        object about 1 minute late on Teds elements and about 10 arc minutes to
        side of predicted track. Track angle matches. In an attempt to get some
        more points on the pass before it went behing buildings I unfortunately
        did not wait long enough to see if the rocket was anywhere near.
        Ive just checked the video and with the time error found now I should
        have seen it but now suspect the point was too close to the earths 
    shadow.
    
    (2) This object looks more like a rocket that a stabilized payload as it was
        showing considerable variability in the few seconds observed as it
        crossed the field of view  (3.2 degrees)
    
    (3) Will try again tomorrow night. Will report observations of other objects
        observed tomorrow.
    
    
    Cheers
    Greg
