Ops Day Shift Summary
TITLE: 05/05 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 67Mpc
INCOMING OPERATOR: Jim
SHIFT SUMMARY: Locked for the entire shift and for ~13 hours total so far. No issues to report.
LOG:
Hugh requests that the HAM2 and 3 GS13 gains be set to correct values at the next Out of Observe opportunity. Contact Hugh for more info.
Jason requests that the ISS diffracted power be lowered to ~3% at the next Out of Observe opportunity.
Both of these items are on the Operator white board.
We had a mystery lockloss just as LLO came back up, so I took the opportunity to address both the ISS diffracted power and the HAM2&3 gains (again). This time, to fix the gains, Dave reminded me the h1fescript0 is still running ubuntu, so I ssh'ed onto that machine and went to userapps/isi/common/scripts and did a ./sensor_hilo HAM2 GS13 hi and a ./sensor_hilo HAM3 GS13 hi. Much easier than last time. The ISS adjustment was straightforward, but we were already at 4%, before I tweaked the voltage down.
