              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Clear skies during the afternoon. Some light cirrus started to pass overhead around 20:00, but the sky remained relatively clear for a couple more hours. Thicker clouds started to roll in around 22:30. By 01:30, the clouds were thick enough that we started having trouble guiding, and clouds continued to be an issue for the rest of the night. We closed up around 06:00.
No problems tonight.
