But because predicted max. duration was 3.3 seconds an ocultation detection would have been possible. Target star 2UCAC 41505354, +13.0mag, 17deg Elevation. Faintest object visible on live video fields (It=640ms) was target star. Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub1.8.6, AviSynth2.5 and Limovie0.9.29b. Predicted event time for observing position was 22:27:36 UTC. No occultation detected (It=640ms) 3-D Position and timing Garmin GPS18x LVC Receiving 07 satellites Horizontal Dilution of Precision 1.2 Geoidal separation 44.5m (Altitude 553.7MSL + 44.5 = 598.2 m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
