Observations with EFOSC2 the all night.
Seeing 1.5" at the beginning of the night, then ~1.0"
EFOSC2 bias; WRONG spectroscopic flat fields and arcs, for a technical problem with the slit wheel the slit was not 1.0"!
We discovered it when we tried to observe the first flux standard

UT 01:45 The telescope operator (TO) checked again the problem with the slit and decided to go to the telescope
UT 02:50 TO back to the control room, slit alignment
