Ops Evening Shift Summary
Ops Shift Log: 06/19/2017, Evening Shift 23:00 – 07:00 (16:00 - 00:00) Time - UTC (PT)
State of H1: Locked at NLN 29.2W, 48.2Mpc
Intent Bit: Observing
Support: N/A
Incoming Operator: Gorey
Shift Summary: After the IFO relocked, ran A2L check script. Pitch is a bit rung up, since we are in commissioning mode decided to run the repair script to make things better.
LLO called about a GRB alert. LHO did not receive notice from Verbal Alarms. In one hour hold.
Around 06:00 (23:00) the ASC Pitch Control and Error signals started to ring up. Could find no apparent reason. Sheila’s aLOG #35371 talks about this and OpLev damping. ITMX and ETMX OpLevs are off center. However, OpLev damping appears to be off on ITMY and ETMY. Range is suffering.
