TITLE: 11/03 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: TJ
SHIFT SUMMARY: Lost lock after 29( I think) hours being locked. Lockloss was probably caused by Dolphin issues(73947), although so far it seems like the issues are documented as occurring 8 seconds after we lost lock, so it's all a bit confusing whether the issues actually caused the lockloss. I had trouble relocking and we kept losing lock at FIND_IR and LOCKING_ALS even after an initial alignment - not sure why that was (maybe related to all the FIND_IR issues from the past few days). We eventually made it back up and just got into Observing. The violins are looking pretty good suprisingly so I will leave the gain for ITMY 5/6 off for now.
