    Identified by Ted as Noss 3-2(C) #28097. Thanks Ted. Was my fault - I had
    not added the LEO satellites in CLASSFD.TLE to my element database :-((
    so #91032 is now considered decayed.

    Notes:
    --------
    
    (1) Suspect satellite reported as #27721 was Milstar 6 rocket.Third position
        not that great - no close reference stars so lens optical defects may
        affect accuracy as near edge of field. Second observation reasonably
        close to centre of field and third position again at edge of field but
        adequate reference stars around it.
    
    (2) Dont know why SIRIUS 3 somewhat fainter than SIRIUS 2.
    
    (3) One of the ASTRA satellites was missing so what is reported as ASTRA 2A
        may in fact be ASTRA 2D which was predicted close to ASTRA 2A.
    
    Cheers
    Greg
