TITLE: 08/06 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Aligning
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

- Arrived with H1 running an IA and trying to relock (following a hectic morning with the high voltage trip, all looks to have been recovered), IA ran without issue

- Acquired NLN @ 0:07, OBSERVE @ 0:22

- Lockloss @ 1:34

- Had to intervene in relocking my moving the DIFF offset by a few steps

- At CARM TO TR there was a message on DIAG MAIN reading "NO IR in arms," couldn't find a reference on how to troubleshoot this and it was stuck for about 15 minutes, so I killed the lock and tried again

• Second time it worked ok, I suspect the issue might have come from the ALS DIFF step not translating right when I adjusted the offset
• Continued instability tonight - multiple locklosses at different states

- After an hour of trying to lock and doing another initial alignment, we cannot even get passed DRMI, I began rallying the troops

• Reached out on MM and contact Jeff/Jim/Jenne (left voicemail)
• Sheila reached out an came out TS to troubleshoot

- We first looked into some odd saturations for PRM/PR3/MC1/MC3 that occurrred @ 23:32/4:14 UTC at DRMI LOCKED CHECK ASC

• Sheila found no evidence of overflows/odd behavior for these suspensions
• Since all these suspensions are under the same model - sush2a, we decided to contact Dave and has not found any issues from the computers
• Sheila wrote an alog on the matter here
