INAF queue observing, 2021 December 20 - December 21

Observer: O. Kuhn
Telescope Operator: S. Allanson
Astronomers from Italy: Andrea Rossi, Felice Cusano, Simona Paiano and E. Marini
Instrument: MODS, LUCI


Due to the covid-19 pandemic situation these observations have been performed by LBTO personel
through the indications of LBT Italian observers (F. Cusano, A. Rossi, S. Paiano and E. Marini) connected from Italy.

We can not use LUCI1 for all the observing run due to a problem with the rotator. LUCI1-AO observations are not possible.
At the sunset the sky is clear, starting observations at twilight. Increasing clouds during the night, stop observations for couds at 4:35.
Opening again at 06:11, then variable clouds all the night.

Night duration (12 degree - twilight) 01:15 - 13:20 UT = 12 h 05m
Observing time: 8h 9min (67.5%)*
Weather time loss: 3h 56min (32.5%)*
Technical time loss: h min (%)*

Additional comments:

** We decided to took a 4th exposure of 600s due to clouds and scattered moonlight, but we accidentally took the 4th spec exposure on the red side only. We resend the acq script and we proceeded to take a single set of exposures, blue & red.
