TITLE: 05/27 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 130Mpc
SHIFT SUMMARY:

Locking:

• Started shift having finished initial alignment. PRMI was locking just fine, but DRMI was not; moved SRM and some PRM to adjust buildups before turning DRMI ASC on. Remainder of locking was straightforward; NLN reached @ 16:30 and Observing @ 16:55 after Vicky fixed a SQZ issue
• Lockloss @ 18:15 from what looked like a CSOFT_P ringup
• Ran initial alignment as ITM camera error signals were far off and ALS Y was having trouble staying locked
• Lock acquisition following that alignment was unaided; NLN @ 20:03 and Observing @ 20:20
• Dropped Observing from 20:49 to 20:52 from the SQZ OPO dropping out; guardians brought everything back on their own

Quiet day otherwise today on site, see my earlier alog about LVEA temperatures over recent days. Handing off to Tony for the evening.
