              ------------- ACTIVITY LOG --------------
Observing Specialist: R.DeColibus
The 3.5m hub computer went completely down at about 17:10, booting everyone off TUI. The hub was not recovered until about 20:00. The problem was traced to a bad network switch. The weather was bad, so we didn't lose any on-sky time.
The weather surprisingly cleared up around 9:45 PM, so we opened up and observed until morning twilight.
