- 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.
