              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had a beautiful mostly clear night, but unfortunately there's still some snow on the roof and the wind gusts were over 20mph all night. We didn't open.
ARCTIC filter wheel (fw5) had same homing problem as a few weeks ago, added to PR2180. Switched to fw2 which did home (and identify wheel) correctly.
