    NOTES:
    ----------
    (1)  Re the two unknowns reported yesterday.
         Mike identified the first one as #37812 11049D - Ariane
         Sylda with very high drag - perigee about 200 kms. The second
         one is a true unknown - the orbit by Kevin is one of MANY 
         possibilities - several were provided by Mike -so chance of 
         recovering it are rather remote. Pity as its a bright object 
         with a low inclination. Mike suspects its an old object.
         Many thanks to Mike and Kevin for their input.
    
    (2)  Quite surprised how bright TDRS 7 was in all three images secured.
    
    (3)  One or two members of the ASTRA group might be confused but not 
         important.
    
    (4) The miserable wet cold weather continues ......
    
    (5) All above measured manually.
    
    (6) The following satellites NOT seen so maybe lost:
    
        FLEETSATCOM 7
        UFO-F03 - seen fairly recently and drifting
        GEOLITE - seen fairly recently and drifting
        SBIRS GEO 1 - believed to be above 88 deg E so current amateur 
                  elements are incorrect.
    
    Cheers
    Greg
