Ops Day Shift End

TITLE: 08/03 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 155Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Currently Observing at 155Mpc and have been Locked for a little over 2 hours. One lockloss today and after some issues with ALS not wanting to stay locked (partially due to ground motion, partially unknown), after an initial alignment we were able to relock fine. We dropped out of Observing once due to the squeezer unlocking but it was able to fix itself.
