Ops Day Shift End
TITLE: 05/07 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 147Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Lighter maintenance today but we managed to do some more SR3/2 moving to investigate our recent required alignment shift. On the relock we had some lock losses that had to be fixed with some filter changes (alog77698). Violins have also come up during these relocks, but they are damping nicely. We are now observing for almost an hour.
