Ops Day Shift End

TITLE: 06/25 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

Currently Observing at 150Mpc and have been Locked for just over 2 hours. Relocking went pretty smooth, with the only issue being DRMI/PRMI taking very long to catch still. During maintenance today, the auxiliary pumps around HAM1 were turned off, and the jitter noise that we had been seeing around 550-600Hz is basically almost fully gone.
