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)
