OPS Eve Shift Summary
TITLE: 07/27 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc
SHIFT SUMMARY: IFO is LOCKED and OBSERVING - same lock as before shift (23:06 UTC)
1. Dust counts in the optics lab were just high for the first 10 minutes of shift - all dust counts now within nominal range.
2. Went out of then back into observing for two seconds at 5:55:54 UTC due to a SQZ lockloss and relock - it was all automated.
3. The new H1_Manager is not giving me any trouble.
