              ------------- ACTIVITY LOG --------------
Observing Specialist: P.Gaulme
Cloudy sky, fast clouds, and radar features prevented me from opening on first half.
In  second half, I opened at 2:25 because it has cleared up for the past 30 min with however clouds crossing. Focus loop done on a 5 mag star. Could not detect he target (13.5 mag). Covered after few other minutes. No science data.
Dewpoint sensor of the 3.5m is still stuck below 0 celcius while it is 1.7 on the 2.5 sensor.
We could have reopened at about 4, for significant clear sky but humidity was too high. We definitely give up at 5am, the observers needing long-exposure times and the weather being too bad.
