              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear with very good seeing.  About 21:00 clouds began to plague us.  The annoying type of clouds where it's perfectly clear between clouds, but the clouds themselves are thick, playing havoc with any kind of guiding you're trying to do as you bounce between losing guide stars alternately from attenuation or oversaturation. Finally cleared out completely around 03:00. Dataq locked up again around 05:00.  Restarted parallels (did not work) and the DATAQ service on hub35m (worked). We observered until it was too bright.
