Summary

At the beginning of the night we stay close due to high humidity. Sky covered. We could perform 4 hours of observation only. We had to stop due to high humidity.

03:50 The TO opens the dome

• Waiting for collimation
• Mirror too warm (DT=4C)

• GILLI

04:40 Slew to Gilli Q2

• the average seeing is 1.7" at the beginning of the integration
• the average seeing is nearly 2" during the first part of the integration of the second frame
• active optics errors, we go on integrating with the last image.

06:14 the TO cancels the preset and tries to collimate, so we have to acquire again. After the collimation the seeing is really better (average seeing 1.2").
