DAY Operator Summary

TITLE: 07/06 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 116Mpc
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:

Very nice shift for H1 with smooth running and only a small EQ which was not an issue at all.  Ended the shift with excitement from a possible BBH candidate with all three detectors online.

H1's been locked for 6+hrs.  Monitored a 5.1 EQ from New Zealand roll through, but did not need to take any action.

Somewhat quiet seismically with the CA 7.1 EQ 12hrs in the past.  Winds are calm. 
QUICK SUMMARY:

H1 humming along just under 120Mpc.  Something new from last time I was on shift a week ago are noisy periods for DARM blrms for the 500-1k & 1k-2k bands (attached) for multiple minutes at a time.

Mid-Shift Update:

Unfortunately, there have been a number of large EQs is California, so H1 is not locked, and I set the Y axis seismic BLRMS's on nuc5 to 1000, when they're typically 3 and 13, in order to capture the peak ground motion activity.

AND... while I was writing that, the IMC locked, with MC1 tripped, taking the IMC to DOWN, and will check the position of the IMC mirrors, since the WFS are engaged with a tripped optic.

ALSO... I went to VERY LARGE EQ as things began to trip, and HAM3 and HAM6 ISIs did not trip, because they made it to DAMPED!

Observing 1613 UTC

After the handoff from Patrick at DRMI, it made it up to DC Readout and then lost lock. The guardian then when through the whole process again without me touching anything.

More SDFs than usual. Normal high precision for PSL ISS and SUS ETMY, as well as the ASC RF36 Q offsets. The odd one was the IMC-MCL_FM_TRIG_THRESH_ON/OFF

Strange, verbal alarms went to ACQUIRE_PRMI from ACQUIRE_DRMI_1F and then back to ALIGN_RECYCLING_MIRRORS by itself
DRMI is not locking, despite PRMI locking
