SCIENCE OBSERVATIONS

UT 0012 - Spec Std: L745a - Gm11/13/16 all with 1 arcsec slit      (15m)

UT: 0025 - Phot Std:  RU152 - UBVRi  (7m)

UT: 0028 - OGLE-2012-SN-006 - UBVRI      (35m)

UT: 0104 - PSNJ06161835-2122329 - 5 x 10s in R to check astrometry    (10m)

UT: 0126 - PSNJ06161835-2122329 - spectra Gm13 1 arcsec slit    (25m)

SNID - classification possibly a Type II? 

UT: 0201 - LSQ13fn - 2x30mins in each of Gm13 and Gm16  (2hr 15m)  

UT: 0300 - cirrus cloud building from south. probably photometric till this point - not after. 

UT: 0400 - cirrus continues to build - so decided to skip the Photo std obs. 

UT: 0420 - Spec Std: L745a - Gm11/13/16 all with 1 arcsec slit  (increased exp time to 240s)    (25m)

UT: 0445 PSN J10011200 0019423 - followup - Gm11 / Gm16   (3h 10m) 

(SNID on this confirms a SN Ia at epoch of ~20)

UT: 0630 - cirrus cloud cleared - looks photometric again. Seeing ~0.7 arcsec

UT: 0800 - PSNJ12393328+1525520 - classification Gm13  (15m)

SNID - possibly a Type II - but featureless. 

UT: 0820 - SSS130221:133330-194457 - classification Gm13 (40m)

SNID - looks like this is an AGN

UT: 0855 - Phot Std:  PG1323 UBVRi  (5m)

UT: 0905 - Spec Std:  EG274 gm11 gm13 gm16  (15m)

UT: 0920 - PSNJ12393328+1525520 - classification Gm13  (22m)

Morning Twilight Calibrations

UT: 0940 - arcs - PESSTO_calib_only_arcs

UT: 1000 - skyflats UBVRi  (~25m) 

End of night - no clouds
