Thursday Operator Summary

TITLE: 01/04 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Aquisition
INCOMING OPERATOR: Corey
SHIFT SUMMARY:

- 16:17 - GRB short E463149

- 16:51 - Superevent S240104b 

- 17:11 - 18:10 - Fire pump testing began - Tagging DetChar in case this shows up as noise on their end

- EX saturation @ 22:02

- 22:35 - went into COMMISSIONING for opportunistic DARM measurements while LLO is down due to microseism

- ISC went through MICH FRINGES a few times without being able to move up, which is my cue to begin running an IA, which is currrently ongoing

- Mystery rise and steady hold of primary microseism is still apparent, coupled with a now rising secondary microseism, I have moved the SEI CONF guardian to USEISM to help make locking less cumbersome
