TITLE: 12/12 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 112Mpc
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
    SEI_CONF state: WINDY
    Wind: 3mph Gusts, 2mph 5min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.68 μm/s

In the last 6hrs microseism has been inching up and it is at/above the 90th percentile.
QUICK SUMMARY:

Received handoff from cheryl regarding H1, violins, PSL chiller & possible noise on DARM.  We can see glitches on DMT Omega in the 20-50Hz band (and this might be noisier on the 20-34Hz DARM BLRMS on nuc23). 

The only GRD User Message is for violin gains not being at Guardian values.

H1's been locked for almost 8hrs.

On a scan of the access system, the middle Roll Up Door for receiving was telling me it was unlocked (yellow), but looked fine on inspection.  I toggled a Force on it (OSB 6750 Diode 172 Lock) & this cleared (green-ed) it up.  Sort of similarly, EY's west exterior vestibule door was in the "stuck open" state (yellow & flash); toggled Force for it and this cleared up.
