              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley, R.McMillan
First half had clouds, a bit of rain, and lots of lightning.  Second half
started out with high humidity (unfortunately not reported by the 3.5m
sensor, but by two others in agreement with each other) and with the
remnants of the storms moving in unexpected directions.  Finally a drier
wind came up from the south and the clouds cleared away, and we were able
to take advantage of unexpectedly good seeing, although it was hard to
follow the focus changes with the telescope far from equilibrium because
the fans were not running during the questionable weather.
