Observers: Stefan Taubenberger, Stephan Hachinger

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

2nd night of 3rd subrun (only EFOSC2).

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 ~30%, wind speed ~4km/s, sky clear

middle-of-night weather cond:  humidity ~20%, wind speed ~3km/s, sky clear

late-night weather cond:       humidity <~20%, wind speed ~5km/s, sky clear
