OPS Eve Shift Summary
TITLE: 08/06 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 149Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:
IFO is in NLN and OBSERVING since 22:22 UTC (6 hr 30 min lock!)
Extremely uneventful shift where we stayed locked the entire time. Range was somewhat low at the start of the lock but picked up and stabilized ~2 hours in.
Temps have effectively stabilized since the drill.
PSL dust was high but this seems to be wind driven and going down. Counts have been higher in last 3 days as well so likely not a cause for concern.
