OWL Operator Summary

TITLE: 07/26 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 53Mpc
OUTGOING OPERATOR: Ed
CURRENT ENVIRONMENT:
    Wind: 12mph Gusts, 11mph 5min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.07 μm/s

useism has drifted down over the last 24hrs to the nice doldrums.

QUICK SUMMARY:

Ed gave me the run down of where we are at. Will keep an eye out for violins. And will address A2L if L1 drops out of OBSERVING.
DARM spectra continues to look noisy post MT-quake (i.e. big table from 10-16Hz & then slightly elevated from 25-1kHz) & have had a few glitches in the opening minutes of this shift.

While performing round of walking the building (mainly turning off lights), a few notables:

PSL Chiller was between Max & Min levels (looked less bubbly than normal). Held off topping since FAMIS task for this is Thursday.
Splattering (photo attached) of drywall near the AED in the OSB (near Fishbowl room). Assume this might be from work above ceiling panel because did not see any mess on the wall above dust pile. I went ahead and used HEPA vac to clean up the pile to help reduce further tracking of drywall down the OSB hall.
