Observations with EFOSC2 all the night.

Log

Dimm-Seeing >1.0" in the beginning of the night; then below 1.0", down to 0.6" at 03:00 UT.

EFOSC2 bias, spectroscopic flat fields and arcs in afternoon

**low clouds**

UT 00:02 EFOSC2 skyflats, aborted because of technical problems, the rotating building can not move, technicians to the telescope

UT 00:35 problem solved, focus and image analysis

UT 00:54 STDPHOT PG0231 UBVRigr

UT 01:03 SN 2013F UBVRi (faint in B, bright in VRi, unclear detection in U band)

UT 01:24 LSQ12hxg UBVRi + gr13 (signal ok, bright Balmer lines in the spectrum)

UT 03:05 OGLE-2013-SN-002 UBVRi + gr13 (strong HII region contamination, broad features at 4600-5000 and 6000 A.)

UT 04:20 OGLE-2013-SN-011 gr13 *classification (young IIP)

UT 05:10 SN 2012hr gr

UT 05:37 SN 2012hs UBVRi

UT 05:55 LSQ13fn UBVRi + gr11 (the spectrum looks like a continuum with a broad emission feature at 7200 A,

no other lines are clearly observed, 2x40 minutes but low S/N, clouds in the sky)

**clouds**

UT 07:45 PSNJ17393154-8518381 gr13 *classification (young IIP, lost guiding after ~30 min)

**clouds**

UT 08:30 STDSPEC LTT3864 gr11+gr13+gr16 / slit 1.0"

**clouds**

UT 08:45 LSQ13fn again gr11 (1x1800), but still a lot of clouds, faint signal

UT 09:20 EFOSC2 skyflats griU (4 out of 5 for i band)
