              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had real weather during the evening, not just threats.  After a heavy downpour the sky cleared quickly, but it was humid and unstable for a while.  The first half observer gave up when she couldn't get a full observation in, so the second half observer got to start early.  And then stop and start and stop again as the clouds did strange unexpected things.  During one of the closed periods several raindrops reached the cloudcam, so it was all justified.
