              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Before opening the humidity was changing rapidly, often but then settled
before sunset.  Towards the end of first half the humidity spiked
suddenly.  Except for brief period of low humidity it stayed high for the
remainder of the night.
First half user performed high altitude (87 deg) transit while observing
(this was known ahead of time).  PMSS looked good throughout, some small
jumps while guiding but nothing out of the ordinary for such a high
altitude transit.
