              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
There was an unseasonal dust storm in the afternoon, so before sunset we were using the handheld counter to check dust levels since the tower counter is out for repairs.  The dust did drop and we were able to open at sunset, but humidity hovered neear the limit for an hour before retreating.  After that it was a lovely night, mostly photometric, with good seeing.
