Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub 1.10.0 and Tangra 3.6.2 Event data details according to the predictions from Occult Watcher Feed IOTA (Steve Preston). Predicted event time was 01:41:42 UTC (+/- 2s) for my observing position. Predicted maximum duration was 3.9 seconds with a 1.4 - 1.8mag drop. Position was 9km from predicted central line in SW direction between path edge and central line with a probability of 75.8%. No occultation event detected (It=0.08s). 3-D Position and timing Garmin GPS18x LVC Receiving 09 satellites Horizontal Dilution of Precision 0.9 Geoidal separation 44.5m (Altitude 548.7MSL + 44.5 = 593.2 m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
