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 00:00 EFOSC2 skyflats UBVRi

UT 00:30 image analysis

UT 00:45 STDPHOT pg2336 UBVRi

UT 00:55 STDSPEC vma2 gr11+gr13+gr16 / slit 1.0", failed, here we noticed the slit problem

UT 01:10 LSQ12dlf R, 6x300

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
