Ops Day Shift End
TITLE: 03/26 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 154Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Commissioning time for three hours this morning, which we stayed locked for. We have been locked for 11.5 hours now. I've been impatient and have tried damping down ITMY violin modes 5&6 by making small gain changes. I think I slightly sped it up, but barely.
LOG:
- 1521-1526 SQZr unlocked, relocked
- 1550 dropped Observing for ~20sec due to an accidental click in the control room
- 1600 Commissioning time start
- 1903 Back to Observing
