Ops Eve Shift End

TITLE: 01/20 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Relocking from the lockloss and currently at PREP_DC_READOUT_TRANSITION. I didn't change the damping for ETMY mode1 officially, but it seems like it will need to be made permanent. Besides the lockloss everything was quiet, I ran an initial alignment and helped ALSY a bit and we have had no issues relocking.
LOG:

21:20 Changed damping for ETMY mode1 to be only FM1 and FM10 (nominal is FM1 FM8 FM10), and gain to -0.2 (same as TJ did yesterday 82340)

04:37 Lockloss
