    Notes:-----
    (1) Two unknowns seen which dont match anything in my element database.
        Would be interesting to know the identity of #91086 which was about
        steady at magnitude 4.
    
    (2) Two possible observations of MILSTAR 5 #27168 which moved recently.
        Was relocated optically by Peter, and also by radio observations - I 
    just
        pointed where they suspected it was.
    
    (3) First observation for me of USA 129 this season-elevation very low 
    before
          going into shadow.
    
    (4) Will report the strays seen tomorrow as I want to set up for tracking
        again tonight.    I also have an equipment problem which has to be
        attended to - the elevation drive is slipping by 2 degrees- something
        loose somewhere.( apart from the loose screws in my "brain"!)
    
    Cheers
    Greg
