TITLE: 03/15 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 143Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Mostly quiet shift with one lockloss and a fully automated relock. I also had to reset the SQZ angle when it ran away. H1 has been locked for 20 minutes.
- 23:17 - Observing
- 03:42 - EQ lockloss - alog83382
- 04:46 - Observing
- 04:49 - Dropped observing when SQZ_MANAGER reported the SQZ angle was out of range, so I requested 'RESET_SQZ_ASC_FDS' as directed by the notification then back to 'FREQ_DEP_SQZ' [Tagging SQZ]
- Before I saw the Guardian notification and I decided to drop observing, DARM looked like SQZ was only injecting noise and range dropped to 70Mpc while still in observing. Would this have stayed like this until someone intervened? Should this be automated to fix this if it happens overnight, even if it means briefly dropping observing?
