Transition To OWL

TITLE: 07/30 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 52Mpc
OUTGOING OPERATOR: Patrick
CURRENT ENVIRONMENT:
    Wind: 10mph Gusts, 8mph 5min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.08 μm/s

Nice & quiet with useism at it's continued low from last few nights with little winds.  The moonset on the shoulder of Rattlesnake just before the strike of midnight was beautiful.
QUICK SUMMARY:

H1 locked for 3.5hrs w/ a range just under 55Mpc.  DARM shows visible higher order harmonics of the violin fundamental (as seen last night), but since everything else looks ok, will not proactively address violins. 

~7:22utc While Patrick & I were chatting happened to notice glitches on DARM, and while typing this write up, it's interesting to see a few minutes of glitches on the h(t) triggers tool.  Basicaly glitches start around 150Hz and sweep down to about 50Hz.  (snapshot attached).
