TITLE: 12/02 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC STATE of H1: Lock Acquisition INCOMING OPERATOR: Jeff SHIFT SUMMARY: Lockloss might be from an earthquake in Japan. Still struggling to relock. After two lock losses in the CARM reduction states, moved to initial alignment. Could not get SRY to acquire in initial alignment and gave up on it to try relocking again. I moved the SEI_CONF state from USEISM to WINDY because the green arms were more stable in WINDY, but have now set it back to USEISM. LOG: 01:24 UTC Dick leaving site. 03:56 UTC Dropped out of observing by squeezer 03:58 UTC Hit INIT on SQZ_MANAGER 04:00 UTC Back to observing 04:40 UTC Changed SEI_CONF from USEISM to EARTH_QUAKE for 4.1 mag earthquake in Canada. 04:41 UTC Dropped out of observing by H1_ISI_ETMY SDF 04:45 UTC Changed SEI_CONF back to USEISM. SDF differences cleared by this. 04:48 UTC Back to observing. 05:06 UTC Changed SEI_CONF to EARTH_QUAKE for 5.6 mag earthquake in Japan. Knocked out of observing by SDF differences again. 05:09 UTC Lock loss. Sudden spike in seismic signal. 05:11 UTC Putting ISC_LOCK in DOWN until ground settles. 05:12 UTC Set observatory mode to earthquake 05:36 UTC SEI_CONF to USEISM 05:38 UTC ISC_LOCK request to NLN. Observatory mode to locking. 05:44 UTC Aligning Y arm for green by hand. Moved ETMY in pitch. 05:52 UTC Lock loss from locking ALS 05:52 UTC SEI_CONF to WINDY 05:59 UTC Lock loss from TURN_ON_BS_STAGE2 06:13 UTC Lock loss from CARM_150_PICOMETERS 06:27 UTC Lock loss from CARM_OFFSET_REDUCTION 06:29 UTC Proceeding to initial alignment 06:45 UTC Set observatory mode to aligning 06:51 UTC Seems stuck on ACQUIRE_SRY ALIGN_IFO to DOWN misaligned SRM AS-AS_C is already well centered realigned SRM requested SRC_ALIGN_OFFLOADED changed request to SRC_ALIGN hit down, init for align_ifo moved SRM in pitch and yaw moved SRM to 1 hour ago skipping rest of initial alignment set observatory mode to locking 07:17 UTC Script moved automatically to ACQUIRE_PRMI 07:18 UTC PRMI locked 07:20 UTC DRMI locked 07:26 UTC Lockloss from CARM_OFFSET_REDUCTION 07:41 UTC Lockloss from DARM_TO_RF 07:42 UTC Set SEI_CONF to USEISM 07:45 Lock loss from FIND_IR 07:56 UTC Lock loss from CARM_TO_TR 07:59 UTC Lock loss from LOCKING_ALS
