TITLE: 03/07 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 63Mpc
INCOMING OPERATOR: Ed
SHIFT SUMMARY: Not a bad maintenance day. Ran initial alignment. Had multiple lock losses in FIND_IR while searching for the Y arm IR. Eventually made it past after sitting at LOCKING_ALS for some time. Kiwamu ran measurements at NLN before going to observing. I have been informed that tumbleweed bailing is ongoing on the X arm. The DMT viewer is not updating the range for LLO: https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=32104 I damped PI mode 28 (or it came back down on its own, not sure if I had any effect).
