TITLE: 12/09 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
INCOMING OPERATOR: Austin
SHIFT SUMMARY: Quiet night with one lockloss (74693) but we relocked quickly and have been Locked for 5.5hours. ITMY modes 5/6 are very slowly going down with the ITMY5 gain set to -0.01, but I will turn this gain off just in case it makes modes 5/6 worse, as it seemed to be doing earlier in the evening before the last lockloss. Here are what they look like right now - the DCPD values have also slowly been drifting further apart as the lock has progressed.

There are also some SPM differences on ITMY (attachment2).
