Operator Report - Morning shift

Upon arrival I found ITF in Science Mode with BNS Range ~51 Mpc.
According with Sorrentino and Tacca; at 10:15 UTC I set ITF in LN3 (Science Mode) in order to take data without SQZ. Then, at 10:23 UTC we close a SQZ shutter for 5 minutes and re opened it at 10:28 UTC. SQZ again injected at 10:32. Science Mode set.
ITF unlocked at 12:54 UTC due to a NI DSP failure (plot1).
ITF relocked after few attempts. Science Mode at 13:58 UTC with BNS Range ~50 Mpc.

GRB
10:45 UTC GRB alert missed. LL1 and LH1 received it. (TBC)
