TITLE: 06/05 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 132Mpc
SHIFT SUMMARY:
- Arrived with the IFO locked and in observing
- Handing H1 off to Ryan S in observing
- Lock #1:
- Acquired NLN @ 13:35, OBSERVING @ 13:51
- EX saturation @ 17:36
- LOCKLOSS @ 18:17 - most likely due to elevated ground motion (local EQ)
- Lock #2-??:
- Had to touch BS in PRMI a hair but it eventually caught ok
- Held in ENGAGE_DRMI_ASC to let ASC signals converge - waited 10 minutes but still lost lock @ DRMI_3f, PRC2 P looked to have the most instability
- Tried a few more times, still didn't work - trying an IA
- Still having issues with DRMI_3f/BS_ST_2 locklosses, Jim is looking into it - FIXED
- Acquired NLN @ 21:19, OBSERVING @ 21:34
