Observers: Daniele Malesani and Kasper Elm Heintz Support team: Paolo D'Avanzo and Giorgos Leloudas TAT: Cristina Barbarino and Janet Ting-Wan Chen
Afternoon: PESSTO calibs and bias
The intention was to continue the SofI observations from yesterday, but the instrument misbehaved once again so we switched to EFOSC around 02:45 UT. We lost about 45 min due to this. The night was otherwise very good with good seeing and clear conditions.
