Because of clouds on western horizon, very bad image quality and long integration time (It=1.28s) a real occultation would have been not detectable. So this report will not be sent to the Plannocult list. Only Clear glass filter (Astronomik) for CCD protection was used Target star TYC 1808-00404-1u, +10.9mag, 09deg Elevation Limit on live video fields was target star. 3-D Position and timing Garmin GPS18 LVC Receiving 10 satellites Horizontal Dilution of Precision 0.9 Geoidal separation 44.4m (Altitude 543.4MSL + 44.4 = 587.8m in WGS84 datum) Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
