Summary
These observations have been performed by Ester Marini and Felice Cusano from the summit of the LBT.
At sunset the sky is clear and we can open. A problem occurred in initializing the camera in LUCI1, with the camera stuck in N30 position. Dave and Jenny tried to solve it but without success, LUCI cannot be used tonight. We used MODS for the whole night.
