Ops Shift Log: 02/10/2017, Day Shift 16:00 – 00:00 (08:00 - 16:00) Time - UTC (PT)
State of H1: Locked at NOMINAL_LOW_NOISE, 30.3 W of power and range of 68.0 Mpc.
Intent Bit: Observing for the past 7 hours.
Support: Sheila, Terra, Jim B.,
Incoming Operator: Ed
Shift Summary: Encountered relocking problems with the OMC LSC_I filter bank, which Sheila resolved. During and after locking worked with Terra to setup Ops StripTools to monitor the two new PI_Modes (Mode19 & Mode20). The PI2_monitoring.stp has been reloaded on Nuc6. Had to damp PI_Modes 26, 27, & 28 several times during the shift. Also took advantage of LLO not having fully recovered from this morning’s lockloss to run the A2L script. By the end of the shift, the A2L Pitch was elevated again.
Sheila & Terra implemented new filters to damp an additional PI_Mode that was implicated in the last two lockloss, (see aLOG #34046 and WP #6474). Dropped out of Observing for 2 minutes to clear SDF differences.
The wind is starting to come up again, now at Moderate to Strong Breeze (13 to 30 mph); End-Y microseism is up sharply.
