TITLE: 09/05 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 150Mpc
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY: Lockloss earlier in the morning was pretty easy to recover from, and commissioning went well
LOG:
14:30 Observing and Locked for over an hour
14:41 Out of Observing due to SQZer losing lock
- We were having PMC PZT volts high notification before it lost lock, so makes sense
14:45 SQZer relocked, back into Observing
15:24 Lockloss, starting initial alignment
15:46 Initial alignment done, relocking
16:05 Lockloss from ENGAGE_ASC_FOR_FULL_IFO
- A few minutes into this state, PR GAIN started falling but Sheila was able to save it by turning off the DARM offset. At this point the AS_AIR spot was looking misshappen, probably due to ASC pushing it in the wrong direction. Then we had the lockloss.
