    Notes:
    ------
    (1) Since the orbital period of #90027 was somewhat uncertain and I had
        not managed to see it on the current elements, I decided to do an
        orbit plane scan and found it with no trouble running considerably
        late. This observation should manage to tie the period down and I
        expect to see the satellite tonight running on new elements I made-
        provided clear of course.
    
    (2) The other satellite passed through the field of view during the
        expected "window" and was initially unknown but subsequently
        identified.
    
    (3) I have still to go through the DVD recording made to identify the
        other satellites seen during the plane scan.
    
    Cheers
    Greg
