              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Variable thin clouds and borderline high winds for much of the night,
with borderline humidity for part of the night as well.  During first
half we closed for a while when thicker clouds and higher winds
coincided; during second half the observer was able to face away from
the wind so we stayed open, but some of the time the clouds made
science impossible.
During a cloudy patch I tried testing a new version of the pointing
correction script, but it hung up early on.  Later I figured out the
fix for that problem but it was not a good time to stop science for
testing.
