TITLE: 11/19 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC

STATE of H1: Observing

INCOMING OPERATOR: Jim

SHIFT SUMMARY: I've been skipping CLOSE_BEAM_DIVERTERS afraid that it would cause the lockloss as Sheila reported in alog31635 when the tidal servo wasn't working. I skipped beam diverters during the most recent lock even WITH the tidal servo working, that was just a habit. I could have gone through PR3 REFL WFS step. Tidal servo didn't work most of my shift until I reverted the tidal trigger thresold (see alog31646)
