              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Another night of clear night and moderate seeing, with both telescope and
instrument working well.  Wind and dust were borderline but we were able
to stay open all night.  I made a seasonal adjustment to the internal
spectrograph focus before the night began, but seeing wasn't stable
enough to get a good determination of whether this improved the slight
disagreement between slitviewer and spectrograph noticed during
engineering a couple of weeks ago.
