                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
First-Half Observing Specialist: Deglman
Grim was not reporting realistic temperatures during the afternoon
checkout.*  Echelle calibration spectra were obtained for JH04.  The
telescope was opened at 17:10.  During opening, one of the mirror cover
panels appeared defective.*  The DIMM was reporting downwards of 0.6
arcsecond seeing, which agreed very well with some echelle slit viewer's
1-second (time) exposures.  Closed at 20:05 due to clouds.  The DIMM and
IRSC were closed at 22:45 due to rain.
Second-Half Observing Specialist: McMillan
Second half was partly cloudy, but we were able to open at 00:30.
There was a little trouble when we tried to take darks with GRIM --
the instrument hung up because the requested exposure times (1.0
seconds) were too short, but it continued to hang up even when the
exposure time was increased.  Restarting the Mac and MC cleared the
problem.  Once we were open, both the instrument and telescope behaved
well, as far as we could tell through the clouds.  The only anomaly
was that the astigmatism seemed to be quite bad even 25 or 50 steps
out of focus.
