Problems: 

Trim=0 at the start of the night. We manually set the value to 1000. Focus was reached after a few short images.

23:41 UT: Missing CCD extensions error. Inddeed, backplane 4 was missing for image 1313347 (S4, N4, S5, N5, S6, N6, S7, N7). Solved with a configure. Did not happen again the rest of the night.

 

Controlling screen with Zoom got VERY slow after ~2am.

 

Comments: 

Engineering night: everything worked well (except the seeing!). Spectrophotometric standard stars in each CCD were taken with filters M411, M464 and N395. In addition a sequence of a globular cluster in N395 was taken to help MAGIC calibration. From 04:00 LCT until the end of the night, KB observed the Fornax field for seach of z-dropouts.
