TITLE: 06/01 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 134Mpc
SHIFT SUMMARY:
Handing off to Camilla
Lock#1:
The failed Coildriver was replaced around 17:00UTC (FRS ticket) and I began relocking, I tried quickly to see if it could get past DRMI but no luck so I went into an initial alignment. During the IA TJ adjusted SRM during SRC align as it was not well aligned.
NLN reaquired @ 18:45 UTC with no interventions. In observing @ 18:58UTC
EX saturation @ 19:33, 20:51, 20:52, 21:07 UTC
I cautiously tried to find a better setting for IY5/6, I first tried stepping up the gain to -0.04 and it brought it down more than twice as quickly (~30%/hour)
