Ops Owl Shift Summary

TITLE: 10/31 Owl Shift: 07:00-15:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ed
SHIFT SUMMARY:
Locked for most of the shift. 4753Hz line was slowly ringing up so I reconfigured the damping filter. Range were up and down likely due to wind. Lockloss seems to coincide with ~40 mph wind gust. PI mode18 rang up once, flipped the phase sign and never saw it again. Verbal alarm complains about TCSY chiller flow towards the end of shift but this is bogus. As Kiwamu requested I also increased CO2 power thoughout the shift, 90 minutes at a time.
