Shift Summary

TITLE: 06/08 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY: Getting back into the swing
LOG:
Jeff & Evan did calibration measurements at the start of the shift. Recovery after lockloss was pretty simple, after doing initial alignment, except Jenne checked the soft error points before the soft loops were engaged. The biggest was about .1 and we survived engaging the loops, but it sounds like it maybe necessary to stop and evaluate when re-locking, for now. PI were also more aggravating than before the pump down. It seems like more modes ring up than before, and mode 28 in particular seems sensitive to phase. The usual sign flip didn't work, but a 10 degree bump and patience were enough.

There are SDF diffs that haven't been addressed, as some need more evaluation, LVEA lights are still on and Corey says the last logged VEA sweep was May 2nd, so we're not going to Observe.

Around 2 UTC, I ran A2L.

 It's been otherwise quiet.
