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

4th regular night of subrun with EFOSC

Observations w/o problems unless noted otherwise (**). Narrowslit acq. for all spectroscopy targets with result y=992 unless noted otherwise (***).

*** Note: one acq. was accidentally done w/o parallactic angle (no spectrum taken after that acq.) -- for that one, a slit position y=995 was measured.

* Note: in all spetroscopy OBs of this night we set "Perform combined offset" in the
  acq. template 
to "F" (false) in order to avoid an unclear telescope/softw. problem

initial weather cond:         humidity ~35%, wind ~ 8m/s, clear sky
middle-of-night weather cond: humidity ~20%, wind ~ 9m/s, clear sky
