TITLE: 08/10 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 151Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY:
Lock#1:
Relocking from the lockloss right before I arrived, couldn't get DRMI or PRMI (No good flashes), went through CHECK_MICH then back to PRMI which loss lock, we then ran an initial alignment which went very smoothly. Back up to NLN at 00:16.
We noticed there was a large line at 102.1Hz upon getting to NLN which seemed to be lowering our range by 5-15 Mpc. It's shrinking as time goes on and our range is increasing as it comes down. There's also something on the 100-450Hz BLRMs during the same time frame, also decreasing. After 2 hours it was back down around if not below the reference
We had a range of 159.15 Mpc for a minute!
We dropped out of Observing due to the squeezer losing lock at 03:47UTC, back into Observing 03:50UTC.
The ISS diffracted power is low, DIAG_MAIN flashes a message about it every few minutes
