Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub 1.10.0 and Tangra 1.4.0.496 Event data details according to the predictions from Steve Preston. Predicted event time was 23:10:42 UTC (+/- 16s) for my observing position. Predicted maximum duration was 5.1 seconds with a 1.3mag drop. Position was 310km from predicted central line in SW direction between 1-sigma and 2-sigma limit with a probability of 2.3%. No occultation event detected (It=20ms). 3-D Position and timing Garmin GPS18x LVC Receiving 07 satellites Horizontal Dilution of Precision 1.7 Geoidal separation 44.6m (Altitude 560.5MSL + 44.6 = 605.1 m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
