    Observations 10 Jan 2006:
    -------------------------------
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa
    
    AMENDED REPORT:
    ----------------------------
    The three UNKNOWNS have been identified by Mike McCants and Scott
    Campbell and proves that once again I make mistakes - it would appear
    that at the time I was measuring these particular objects I had the
    wrong element database in GUIDE. I have two databases I use- one has
    about 9000 satellites, the other 150 and I would normally use the
    9000 one but seem to have used the 150 satellites instead.
    
    Here are the correct identities
    
    #91054 = SL-8R/B 87051J
    ---------------------------------
    Fairly bright and steady

    #91055 = SICH-1M  04052A
    -----------------------------------
    Bright and steady

    #91056 = SL-14 R/B  94086G
    ------------------------------------
    Faint and variable
    23447 94 086G   0433 P 20060110201412900 56 15 1957263-715554 39  +080 05

    NOTE:
    -----------
    The observation reported as #90042 is in fact NSS703 (#23305) which is
    near
    by. Here follows a correct observation of the two objects
    
    90042 05 828A   0433 P 20060110194240000 56 15 0709349+055307 39  +115 05

    Mike spotted this....
    
    My sincere apologies to all for my mistakes and many thanks to Mike and
    Scott for
    their input.
    
    Re the unknowns: I should have realised at the time that something was not
    100% - one unknown is possible but three in the space of a few minutes? I
    will in future check possible unknowns against the full element database
    using one of the many programs available that does this task.
    
    
    Cheers
    Greg
    
    PS.
    I have decided to keep a log of my mistakes for 2006: :-)))
    GR001    09 Jan - lost nearly 4 hours of observations recorded to DVD due
    to
                   carelessness by me causing a power failure.
    GR002    10 Jan - Unknowns  #91054,91055 and 91056 were NOT Unknowns-
                    I used the incorrect element database.
    GR003    10 Jan - misidentified NSS703 and #90042.
