    Notes:
    ------------
    
    (1) Purpose of the observing session was to do a plane scan for #90044,
        which was unsuccessful, and to observe #90006 which has just begun
        visibility at my location.
    
    (2) An unknown was found during the plane scan and I find no match in
        my element database. Satellite was about mag +7.5 and essentially
        steady with perhaps very short period variations in magnitude of
        small amplitude.
    
    (3) #90006 easy object - variable ( few seconds max) but bright.
    
    (4) USA 129 not currently visible from my location anymore ( unless
          I blow up my house and the next door neighbours as they are in
          the way.
    
    Cheers
