              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
The night was uneventful on the 3.5m, but around switchover ARCSAT/Surveycam stopped working and bested all of my attempts at troubleshooting.
Intermittent clouds showed up occasionally during B-half, but otherwise the sky was clear. The clouds were a little worse after about 4:30, but were moving very quickly. We closed up around 07:00.
