                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
1st half observing specialist: Deglman
The telescope was not opened at dusk due to high winds, humidity and
cloudy skies.  Kevin Krisciunas lost flats and UW07 due to weather.
Craig Hogan lost UW11 due to weather. The time was primarily spent
analyzing the most recent echelle slit viewer upgrades, which more
limit the exposure time to avoid unfortunate consequences of user
error.
2nd half observing specialist: McMillan
The telescope was not opened during second half, due to clouds, high
humidity, and blowing snow.  The snow was light enough that we didn't
run the snow program during the night, but did leave the enclosure
facing south for the day and the roof heaters on to ensure no ice on
the roof.
* After several nights when observers noted that counts from the
echelle quartz lamp were far below normal, we checked inside the
echelle front end and found that the lamp was just slightly out of
alignment.  It had probably been knocked when adjustments were made to
the shutter a couple of weeks ago.  The lamp is now properly aligned,
and echelle observers should return to the normal integration times
for quartz flats (approx 6s unfiltered, 180s with blue filter).
