SHIFT SUMMARY:

Recovered from the earlier lockloss!
An Initial_Alignment was ran, and we got back up to Nominal_Low_Noise at 20:46 UTC 
I did have to accept some SDF diffs for the SEI system, and reached out to Jim about it. He mentioned that the some of those channels should not be monitored.
When the SEI ENV went back to calm, and it dropped us from Observing a few moments later we unmonotored those channels.
We got back to Observing at 21:04 UTC

21:10 UTC we fell out of Observing because of a SQZ issue, returning to Observing at 21:24 UTC


SUS ETMY Roll Mode is growing!
H1:SUS-ETMY_M0_DARM_DAMP_R_GAIN was changed to account for an interesting Roll mode on ETMX, and accepted in SDF. YES, Ya Read That Correctly and I didn't make a mistake here. Changes to ETMY  damped a Roll mode on ETMX .
The Ops Eve Shifter should revert this change, before handing off the IFO to the Night Owl Op.

H1 has been locked for 2 hours and 40 minutes and is currently OBSERVING.
