              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
A pretty uneventful night. I noticed that the optical cloudcam hadn't updated properly since the 13th and wrote a PR about it. Otherwise, the sky was clear as crystal most of the night, with variable seeing. Some clouds started to pass overhead around 04:00. We closed up around 06:00.
