              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear and dry, but with an easterly wind that ruined seeing.  It was discovered around 23:00 that the transit imaging had been going on without the diffuser (seeing was so bad that diffused and undiffused images looked the same unless closely examined).  Observer called it quits and logged off.  We did one observation for Drew's program (NM04), but we could not find any takers for the remainder of the night and so we went back to NA03's target, which was mid-transit, and did our best to pick up where it was left off, this time with diffuser engaged. We stayed on it until the target reached airmass 3. Seeing did improve after midnight.
