              ------------- ACTIVITY LOG --------------
Observing Specialist: M.Croom
Lots of clouds and radar that seemed to be leaving as APOLLO was scheduled, but new radar returns kept cropping up. Radar finally cleared out at midnight, and we got on-sky with ARCTIC. ARCTIC had mostly good weather with okay seeing, and finished with sky flats and darks.
No telescope or instrument issues.
