              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
First half had clouds, threat of rain, and actual rain.  Second half started out in the same vein but once the threat improved I thought it was worth taking a chance.  There was some clear time with decent seeing, and some partly-cloudy time with pretty bad seeing, but overall second half was useful.  Everything worked well.
