              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Super thick clouds and radar all night due to the incoming snowstorm.
KOSMOS slits have been relabeled and I took KOSMOS internal spectrograph focus measurements as well as a set of flats to check the instrument shutter.
No telescope or instrument problems; telescope is parked with the altitude strap.
