TITLE: 08/20 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Jim
CURRENT ENVIRONMENT:
Wind: 7mph Gusts, 4mph 5min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.09 μm/s
QUICK SUMMARY:
As Jim and I were chatting before he left, H1 broke lock! (No obvious seismic reasons or anything else seen for a cause). Currently taking back up.
Notes On Relocking So Far:
It's been a couple of weeks since I've locked.
The PRMI cavity looked dead at first, so I went to CHECK MICH FRINGES, & it still looked like it was in the doldrums, but managed to see that it needed some BS YAW---miraculously PRMI then locked on the quick.
As TJ noted, AS90 is different (for the PRMI locking steps, it is up around 2000 counts [just barely visible on StripTool], so I ignored that channel). The PRMI/DRMI transition looked odd/slow motion during the transition, but made the switch without breaking lock.
Other than that, had no issue with getting back to OBSERVING.
