              ------------- ACTIVITY LOG --------------
Observing Specialist: M.Croom
C.Gray(support ObsSpec)
We had a few hours of high humidity following sunset, but the humidity dropped a couple of hours later and had good conditions the remainder of the night.
However, the telescope was not available for the observing programs tonight as there is snow on the enclosure. Still, Candace was able to hold remote training for OU04 and they got to exercise the Echelle and KOSMOS in the closed dome.
With no observers, I waited until after 4:00 to call it quits primarily to space out the LN2 fills.
No telescope or instrument issues tonight.
The telescope is parked facing south to aid in melting the snow off the roof.
KOSMOS remains mounted since it is scheduled for tomorrow night.
