MDM Observatory 1.3m Telescope Observer's Report for 2000 Dec 14

Observer(s): Halpern
Institution(s): Columbia

Instrument: Nellie Direct

Worked for 13 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the summary for details.

Seeing and Weather:
   Beg: Seeing 2.5 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.3 arcsec, Clear, Winds Calm
   End: Seeing 2.5 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

Observed a single GRB field most of the night.

The telescope made a small jump at about 1h56m west of
the meridian so that the star landed just outside of
the guide box.  I seem to recall that this was a recurrent
event on a TIFKAM run not too long ago.  Was it at the
same hour angle?  I'll have to ask Gary Wegner.

Possible occultation of the CCD by the finder mirror is
reported in a separate trouble report.  The finder mirror
may be having problems moving all the way out.
