Ops Shift Log: 12/16/2019, Day Shift 16:00 – 00:00 (08:00 - 16:00) Time - UTC (PT)

State of H1: Locked at NLN, range is currently 113.1Mpc  

Intent Bit: Observing  

Support: N/A

Incoming Operator: TJ

Shift Summary: LHO went out of Observing for about 1 minute while Jenne turned off CPS DIFFs. Other than this, we have been observing for 39.5 hours. Microseism is elevated and growing. The range has been lowish (100 to 107Mpc) at times, which may be due to the microseism. Other than this all is well.
