              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Rain and clouds and especially high humidity.  The dewpoint did drop for a couple of hours, but the clouds were very thick for most of that.  When the clouds progressed to medium-thick I tried opening, but there wasn't even enough time to get focused on a very bright star before the humidity spiked again, so I didn't count any of that time as usable.
The humidity doesn't look so high in the log below because that sensor was frozen, and one of the others was also having trouble, but that still left two in agreement that the humidity was very high, in addition to the evidence of visible fog.
