Ops Day Mid-Shift Report

H1 returned to observing at 19:54 UTC after a fairly strightforward relocking process. DRMI took a while to catch, but once it did, we paused to take a few OLG measurements (alog87768).

The 1 HZ ASC ringup started right around reaching low noise. Elenna tried a couple things to mitigate it, but we eventually just transitioned to high-gain ASC to finally subdue it.

I had one SDF to accept (see screenshot) which appears to be from Tony's SQZ troubleshooting overnight (alog87760).
