- Evening session (3.0hr), good conditions to begin, but cloud rapidly covered the entire sky after 3 hours forcing a premature abandonment of the session. - CCD operation of -20 degC (at 60% average cooling). - main objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis, in particular Z And and RU Peg - secondary objective was to acquire a mosaic of 8P/Tuttle passing by the large spiral galaxy M33 in Triangulum - unfortunately cloud developed just as the mosaic commenced and the attempt was abandoned.
