TITLE: 12/25 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 114Mpc
OUTGOING OPERATOR: Niko
CURRENT ENVIRONMENT:
    SEI_CONF state: WINDY
    Wind: 3mph Gusts, 1mph 5min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.51 μm/s

Microseism is at a high-ish level, but not seeing tons of glitches on DARM's "microseism shelf" (which are glitches hovering around 15-30Hz).  Will continue to watch DARM to see if we want to take SEI_DIFF to the DOWN state (Jenne was swaying away from us needing to go DOWN if microseism BLRMS is above 0.04um/s (which we're currently at).
QUICK SUMMARY:

H1's been locked for almost 8hrs on this Christmas holiday.  Our range is a little lower than we were at a few days ago, but the Earth's been a rumblin'.

And on this holiday, looks like Richard has set up the Access System to keep all of our exterior doors buttoned up (I even tried swiping in to multiple doors after 8am & they remained locked after entering (but one should continue to check the doors via the Access System for one's own piece of mind.)
