              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,A.Townsend
We were able to open soon after sunset with clear skies and moderate seeing, but the east wind picked up and nearly got to the limit before settling down a little.
No telescope or instrument problems.
