              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
There was threat of rain at the start of the night but we were able to open not too long after sunset.  A few clouds came through but never got too thick to observe through.  Then during the wee hours the humidity began to rise.  I pushed it as far as I could since surfaces in the dome were fine, but eventually with all sensor agreeing that it was too humid, I closed.  After that, the humidity kept pretending to go down and popping up again, until it was twilight.  And then it dropped for real, just to taunt us.
