TITLE: 05/19 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Relocking
SHIFT SUMMARY:

Main Notes:

- The LSC feedforward measurements have been completed and results can be accessed in /ligo/home/elenna.capote/LSCFF on any CR computer - Tagging ISC

- nuc30 has been power cycling for some reason and when it comes back up the displays are mirrored instead of separate displays

- Just finished up recovery and an initial alignment from the EQ and leaving the IFO in the process of relocking (currently at OFFLOAD_DRMI_ASC) with the OBSERVATION bit set to automatic to hopefully go straight into OBSERVING once it acquires NLN

- IFO has been locked for 3:49 and in OBSERVING at the start of my shift

- Some SQZ changes came up that took us out of OBSERVING, talked with SQZ and accepted - ss attached

- EX saturation 0:18/1:05

- 1:44 UTC - I am taking the IFO into COMMISSIONING to run LSC FF tests (permission was granted from Jenne) - finished right before the EQ

- 1:58 - EQ from New Caledonia (same place as yesterday) - 7.1 mag

• Holding in DOWN to ride out the ground motion
• 5:17 - ground motion has went down a sizable amount, and aftershocks seem have subsided - beginning to untrip WDs and start an IA
• Had some issues again with ALS Y drift again - this time with ALS_Y_DOF_1_P
• After a bit of touching Y arm suspensions and letting the ground settle a bit more, I was able to get it locked - IA completed
