Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub 1.10.0, Tangra v1.4.0.499 Event data details according to the predictions from IOTA (Steve Preston). Predicted event time was 22:48:55 UTC (+/- 73s) for my observing position. Predicted maximum duration was 40.9 seconds with a 4.6mag drop. Position was 197km from predicted central line in NNW direction between path edge and 1-sigma line with a probability of 13.9%. No occultation event detected (It=0.160s). 3-D Position and timing Garmin GPS18x LVC Receiving 09 satellites Horizontal Dilution of Precision 0.9 Geoidal separation 44.5m (Altitude 545.1MSL + 44.5 = 589.6 m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
