Ops EVE Shift End

TITLE: 04/19 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Currently Observing and have been Locked for 36 minutes.
Two unknown locklosses during my shift. The lockloss tool flagged the first one as windy, but since the wind went just above 20mph 4.5 minutes before we lost lock, I don't think that is the reason. The second lockloss had a set of small glitches in the 300ms before the LL(attachment).
