Observers: Stefan Taubenberger, Stephan Hachinger

Data reduction team: Nancy Elias-Rosa, Antonia Morales-Garoffolo

3rd night of 3rd subrun (only EFOSC2) -- last night of run.

All observations turned out to be good quality unless noted otherwise (**).

All acqusitions for spectra with NarrowSlit template, slit stable at y=992.

Note: airmass values are estimates based on visibility chart (exact vals pls see files) -- this has been the same in our other night reports.

initial weather cond: humidity ~15%, wind speed ~8km/s, sky clear

middle-of-night weather cond: humidity ~10%, wind speed ~12km/s, sky clear

late-night weather cond:

early eve calibration OBs:

domeflat-specpol, arc-specpol

(slitpos-specpol not done: yesterday slit pos. turned out OK w/o check OB)
