Observations 27 Feb 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.

This time Ivan Artner discovered DSP like radio signals in the vicinity of #90041 but his antenna bearings indicated it was not #90041- times of shadow entry did not correspond either. (2) An optical search of the suspect area revealed the above object which shows DSP like optical characteristics. Through the marvels of the Internet Peter Wakelin was also able to locate the object. (3) My magnitude estimates may be a little out- I was observing through light mist at an elevation of 17 degrees and into the bright sky glow of Cape Town (I live in the middle of Cape Town surrounded by freeways). (4) I could not see #90041 even though I was looking at the predicted location so it was in its dormant "flashing" state. This one is fussy about phase angle for flashes!
