                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
SPIcam temp 190.1K @ 18:00
SPIcam temp 186.1K @ 05:30
 We had rising humidity but I opened for a few minutes at the start of the night so my observer
could get a high priority target.  Humidity quickly rose and we closed after the observer got
their 10 min exposure.   Rain started a couple hours later as we had a thunderstorm move thru.
Humidity and clouds kept us closed the remainder of the night.
We gave up around 05:30 with fog and high humidity.
