TITLE: 05/07 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 127 Mpc
SHIFT SUMMARY:

Main Notes:

• IFO is locked at NLN and in OBSERVING
• DRMI locking was not as big of an issue as it was yesterday, but still needed to manually touch up PRM/BS
• High ground motion at end stations, and high wind (~40 mph)
• I have not done an IA today, but we should keep note that we have been having issues trying to ACQUIRE_XARM_IR over the past couple days when attempting one

Lock #1:

- Acquired NLN @ 15:33

- PI 31 ringup @ 15:39, PI 24 @ 17:25/17:44/18:17 - no intervention needed

- IN OBSERVING: 15:57, taken out @ 17:03 by VAC CP1 channel - Screenshot attached, back to OBSERVING @ 17:08

- EX saturations @ 17:16/20:03

- LOCKLOSS @ 20:34 UTC - Unsure what caused this one, could have been an ASC ringup, but could have also been due to an uptick in local ground motion at the end stations - ASC plot attached
