- 20:00 PESSTO_bias, PESSTO_calib
- 23:57 Sunset
- 23:30 PESSTO_SkyFF UVi
- 09:30 PESSTO_SkyFF BR

SCIENCE-OBSERVATIONS:

EFOSC observations  

- 00:54 AS14kp, Airmass=1.6, Seeing=0.7”
Comment: followup gr13 2x2700
- 02:40 14gqk, Airmass=1.17, Seeing=1.05”
Comment: followup gr11 1800 + gr16 1800 
- 03:45 Image analysis re-done
- 04:03 OGLE73, Airmass=1.3, Seeing=variable
Comment: 2x3200s gr13, with offset between exposures. When doing the acquisition seeing was ~1”, then it jumped around wildly during the first exposure. Was under 1.5” for the second. Stacked signal looks OK.
- 06:11 STD Airmass=1.15, Seeing=1.08”
- 06:43 OGLE73, Airmass=1.75, Seeing=0.87”
Comment: photometry followup BVRi
- 07:40 2014ad, Airmass=1.08, Seeing=1.32”
Comment: followup photometry 10x30 r-band
- 08:00 PSNJ13, Airmass=1.4, Seeing=1.21”
Comment: followup gr11 1600s + gr16 1600s
