Ops Shift Log: 02/19/2017, Evening Shift 00:00 – 08:00 (16:00 - 00:00) Time - UTC (PT)
State of H1: Locked at NLN, with 64.9 Mpc of range.
Intent Bit: Observing
Support: N/A
Incoming Operator: Corey
Shift Summary: A2L DTT script shows pitch elevated between 20 and 25 Hz. Will run the A2L script if LLO drops out of lock.
Mostly a smooth shift. Have been Observing for the past 22.5 hours. With the exception of A2L pitch, the interferometer has been humming along all shift. There was a GRB alert, which LLO received but LHO did not. As both sites were in observing, observed the one hour stand down. Environmental and seismic conditions remain favorable.
