TITLE: 10/25 OWL Shift: 23:00-7:00UTC
STATE of H1: Locked low noise ~75 Mpc
Support: Sheila & Evan
Quick Summary: Violin modes were handled just in time for the winds to pick
Shift Activities:
When I arrived IFO was in corrective maintenance while Evan & Sheila worked on ETMY. Spent the next six hours trying to damp them down and keep the IFO locked. Lost lock a couple times for reasons unknown. Microseism is high, trending up, winds are gusty, BSCs are running 45mhz blends, so this may not go well. POP_AIR is showing large low frequency fluctutations typical of the 45mhz and ASC yaw loops are not happy.
