              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart, R.McMillan
Widespread clouds at the start of the night, annoying but not dangerous.
The first program was able to get half their desired targets.  The second
program also struggled initially, but then wind shifted, clouds cleared,
dust and humidity rose. When the telescope cooling caught up with the air
temperature, we had to close. Weather improved by 2:20, and we opened
again to moderate seeing and calm conditions. No problems the remainder of
the night.
