              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had rain at sunset and some more sprinkles in the middle of the evening, but there were gaps where I felt able to run the fans for a while or open the cloud camera.  Second half the clouds started to clear, then clouds and humidity alternated for a little while.  By 4 am I thought it was actually worthwhile to close - it was almost too late to get anything useful on the science target, but I got some data anyway, and hopefully it will be useful.
