Night report page - 20130413


Observers: Stefan Taubenberger, Stephan Hachinger
Data reduction team: Nancy Elias-Rosa, Antonia Morales-Garoffolo

3nd/last night of 2nd subrun (only EFOSC2).
All observations turned out to be good quality. Airmass values are quite approximate because of changes w/r/t the original schedule.
All acqusitions for spectra (except for stdstars) with NarrowSlit template, slit stable at y=992.

initial weather cond:          humidity ~17%, wind speed ~5km/s, sky clear
middle-of-night weather cond:
  humidity ~10%, wind speed ~8km/s, sky clear
late-night weather cond:       humidity ~10%, wind speed ~3km/s, sky clear 

UT ~21:30   PESSTO_bias, etc. executed by technicians

UT ~22:40   start of night: skyflats UBVR (UVRi see last night)
