Only Clear glass filter (Astronomik) for CCD protection was used. Video evaluation accomplished with VirtualDub 1.10.0 Prediction data used from EAON. Predicted event time was 21:45:35 UTC (+/- 17s) for my observing position. Predicted maximum duration was 1.3 seconds with a 5.8mag drop. Position was 9km from predicted central line in W direction between path edges with a probability of 3.0%. No occultation event detected (It=20ms). 3-D Position and timing Garmin GPS18x LVC Receiving 09 satellites Horizontal Dilution of Precision 1.0 Geoidal separation 44.5m (Altitude 554.4MSL + 44.6 = 599.0 m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
