Ops Shift Log: 03/13/2019, Day Shift 15:00 – 23:00 (08:00 - 16:00) Time - UTC (PT)

State of H1: Locked at NLN

Intent Bit: Maintenance

Support: Jenne, Sheila

Incoming Operator: N/A

Shift Summary: The recovery from the 16:23 lock loss was difficult due to the SR3 heater being on at the lockloss. Tried relocking with the heater still on without success. Turned off the SR3 heater and after things cooled down and several rounds of alignment adjustments and relocking attempts, the IFO relocked at NLN, with a range of around 85.7. Turned the IFO back to the commissioning team.
