Ops Day Shift End
TITLE: 03/26 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Maintenance day activities concluded just before noon and we made it back to low noise at 21:11 UTC. Since then there have been detchar injections, PEM inj, PRM/PR2 spot centering.
- First lock attempt
- Ran an initial alignment, no issues
- Made it up to Transition_to_ETMX before it lost lock. Violins were a bit high on ETMX, but can't say that this was the cause.
- 2nd
- Waited at 2W DC to damp violins a bit before moving on
