Night Report 2018-04-20

Support team: Paolo D'Avanzo and Giorgos Leloudas

TAT: Cristina Barbarino and Janet Ting-Wan Chen

Morning: SofI + PESSTO calibs

Afternoon: PESSTO calibs and bias 

The intention was to have the first half night with SofI, but after the first couple of observations the frames showed lots of electronics noise. This seems a well-known problem with SofI, but the quick-and-dirty workaround did not succeed. We thus switched right away to EFOSC.

The night was otherwise very good with good seeing and clear conditions.
