Shift Transition - Owl
TITLE: 04/20 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 61Mpc
OUTGOING OPERATOR: Patrick
CURRENT ENVIRONMENT:
Wind: 26mph Gusts, 22mph 5min avg
Primary useism: 0.10 μm/s
Secondary useism: 0.19 μm/s
QUICK SUMMARY:
H1 freshly re-locked. Modes damped as per Patrick's aLog. a2l shows ETMX out in YAW by ~.68. Will run the dither script at my first convenience.
50 minutes later, the notion of running a2l is no longer necessary. It seems the loops have pulled the alignment together quite nicely. ETMX f1 Mode4 was rung up pretty good but is slowly ringing down as are it's counter-parts. Bounce and Roll have also diminished well below reference. Range is averaging ~ 60Mpc. Winds are ion the 20mph range.
