Observations 08 October 2011 -------------------------------- Cosatrak 1 (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 ~100mm focal length f/2.8 lens,integrating for 128 fields which is equivalent to a max exposure of 2.56 seconds maximum per image, but dependent on sky brightness. Field of view 4.2 x 3.1 degrees - monitor shows stars down to mag 11 so LEO limit in non-tracking mode about 7.5 mag. Auto tracking mode gives another 2 magnitudes gain. Individual frames are video time stamped with GPS derived signal. Images measured manually from DVD recording using VLC program.

(2) NOSS 0r seen by accident low in south - bright city lit sky made exact determination of end of trailed exposures a bit difficult. (3) Same story with OTV-2 - very low elevation <14 degrees) so had to get in gap between local buildings (4) NOSS 2-3(E) very faint and variable - had to use autotracking mode which increases magnitude about 4x (5) NOSS 2-3(C) also a bit faint - had to use autotracking mode (6) NOSS 2-3(D) relatively easy - some nice flashes - one to about mag +1 or +2 - maybe regular variation. Obviously the NOSS 2-3 series are no longer operational or stabilised. (7) NOSS objects with no magnitude because auto tracking mode used so difficult to estimate brightness (8) MENTOR 2 still drifting. (9) USA 129 seen but too faint to measure as already in shadow when it cleared local building.
