TITLE: 12/06 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 59.5354Mpc
INCOMING OPERATOR: Jeff
SHIFT SUMMARY: Aside from one lockloss that I can't explain, we have been locked the whole shift. The range fell starting around 12:30 and has come up a bit, but not fully. I have ran the DARM_a2l_passive.xml every once in a while and it came out with different results almost every time. So I wasn't sure if I should run it in the beginning of the shift, but I ran it after LLO dropped out and the range wasn't recovering. Not sure if it helped.

TCSY chiller flow has been an issue throughout the night, but seems to get stable for a few hours at a time.
