WATEC 902H + FD 1.8/50 mm + TANGRA astrometric software, UCAC-4 star
catalogue, GPS time inserter

-------------------------------------------------------------------------

Nice clear sky. Observed two passes.

During the first pass it was an easy naked eye object, attaining mag +2.5.
During the second pass, higher in the sky, it was fainter, but still well
visible by the naked eye at mag +3.

I noted that TANGRA underestimates the magnitudes at such brightness, so I
omitted them from the report.

During the first pass it was 0.08 seconds late, during the second pass 0.15
seconds late with regard to Ted's elset. The first pass at lower elevation was
slightly off-track (0.03 deg), the second higher pass was on-track
