              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Elevated dust at the start of the night.
The dust counters went offline a little before 4AM.  Since dust had been pretty constant, high but below limits, and the humidity was low, I kept us open.
No telescope problems tonight.
