              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Like last night, clouds and nearby precipitation cleared up rapidly once the sun had set.  We were actually able to open in twilight.  The weather improvement wasn't quite as complete as last night, however - wind was from the east, seeing was poor, and during second half there was a humidity spike that caused us to close for about an hour.  But it was nice clear weather and pretty productive in spite of the seeing.
