Comments: 

Calibrations in the afternoon are bad, they have not structure, like bias. I checked the calibrations at the end of last night, they started fine, but from file 1127(bias) there are not structure in the files. I re-started the GUI and the problem was solved. 

NLTTT44988AB: seeing worse than required (> 1.5", check the headers), even tough this seeing I observed each component individually using a field star for guiding.

RKS0002-6816: Two stars overlapped.

At 04:30 UT the fog covered the mountain very quickly, it stayed by about 30 minutes, but he humidity was in the limit by about two hours.

No data from the DIMM monitor the second half of the night.
