              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
No luck tonight. Stayed closed during A half due to nearby rain, and it was cloudy anyway.
Noticed that Dataq had frozen around 23:45 or so, a restart fixed it.
The B-half observer took cals. I briefly hoped the weather would clear enough to open around 03:30, but then a drizzle formed on top of us.
We did not open all night.
