    Observations 26 Mar 2007:
    ----------------------------------
    
    Cosatrak 2 (Computerised satellite Tracking System).
    MINTRON low light level CCD surveillance camera (0.005 lux typical
    in non integration mode) and 0.00005 lux in STARLIGHT mode with 128
    frame integration.
    
    Used with 150mm aperture f/5 Celestron reflector on Vixen Super
    Polaris equatorial mount used in alt-azimuth configuration and fitted
    with stepper motors on azimuth and elevation axis. Integrating for
    96 frames which is equivalent to an exposure of 1.92 seconds per image.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa

    Notes:
    -------------
    
    (01) #91096 - maybe slight variability
    
    (02) #91097 - minor slight variation, infrequent weak flash
    
    (03) #91098 - in CLASSFD.TLE as #90073
    
    (04) #91099 - if memory correct now too low in west and drifting west.
    
    (05) #91100 - slight variability
    
    (06) #91101 - slow variability about mag +12.5 to +14-no flashes seen
    
    (07) #91102 - slight variability
    
    (08) #91103 - basically steady and bright- mag +10
    
    (09) #91104 - variable, flashes weak but fairly frequent
    
    (10) #91105 - mostly invisible then slow increase to about mag +10.5
    
    (11) #91106 - maybe slight variability
    
    (12) #91107 - essentially steady - no flashing seen
    
    (13) #91108 - short period (few seconds?) small amplitude variation
    
    (14) #91109 - if memory correct now too low east and drifting east.
    
    (15) #91110 - flashing magnitude +11 to about mag +14 - might be DSP??
    
    (16) #91111 - quite variable, mag 10.5 to +14, period around a minute.
    
    (17) #91112 - slight slow variability
    
    (18) #91113 - essentially steady
    
    (19) #91114 - bright and steady
    
    (20) #91115 - variable, short period?
