              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
After a period of clouds and nearby rain at sunset, we were able to open
near the end of twilight.  All was peaceful for a few hours, then a very
frustrating weather pattern started up with few or thin clouds onsite, but
believable fast-moving radar returns too close for comfort.  We did
actually get a few light sprinkles of rain to justify remaining closed for
some hours.
When we were able to reopen, the unsettled weather showed in worse seeing
and some waves of clouds, but at least it was possible to get some
observations.
