    in non integration mode) and 0.00005 lux in STARLIGHT mode with 128
    frame integration.
    
    Used with 50mm focal length f/1.8 lens,integrating for 128 frames

    Notes:
    -------
    
    Same unknown as reported yesterday- this one isnt going to get away!!!
    The above positions were obtained as it crossed the field of view of the
    ccd camera. It appeared steady at about 7.0 ( yesterday I said about
    mag 5 but on account of the integration and slow movement my guess was
    probably too bright so this is more realistic).
    
    A rough calculation indicates an inclination of around 43 degrees, RA
    Node about 162 degrees, range ~6000 kms so standard +3.0
    
    Another unknown will NOT escape!!!!!
    
    
    Cheers
    Greg and Art ( who nagged me to try for it again!)
