Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub 1.10.0 and Tangra 3.5.8 Event data details according to the predictions from Occult Watcher Feed IOTA (Steve Preston). Predicted event time was 21:07:42 UTC (+/- 10s) for my observing position. Predicted maximum duration was 1.7 seconds with a 8.6mag drop. Position was 36km from predicted central line in N direction between path edge and 1-sigma line with a probability of 9.2%. No occultation event detected (It=0.02s). 3-D Position and timing Garmin GPS18x LVC Receiving 10 satellites Horizontal Dilution of Precision 0.8 Geoidal separation 44.5m (Altitude 548.5MSL + 44.5 = 593.0 m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
