                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
SPIcam temp 171.0K @ 17:30
SPIcam temp 167.5K @ 04:30
The 2nd set of mirror covers did not fully open at the start of the night during checkout.  I
cycled them closed/open, via computer, and they worked fine afterwards.  Just a glitch I guess.
Humidity was high during the start of the night but we were able to open for the first 2 programs,
just after the start of the 3rd program for the night the humidity went over the limit and we
closed.  Remained that way the remainder of the night.
With clouds, rain, fog, and high humidity I gave up around 04:45
