Ops Day Shift Start

TITLE: 11/25 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 4mph Gusts, 3mph 3min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.21 μm/s 
QUICK SUMMARY: H1 is observing and has been locked for almost 13 hours. In and out of observing overnight due to PEM and SQZ tests. DIAG_MAIN reports the CO2 lasers aren't at their nominal power, which I know was changed as part of a script overnight. Maintenance day today; the list seems relatively light.

Lost lock at 15:58 UTC, assuming due to people out in the LVEA near BSC1/2.
