TITLE: 05/25 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Observing at 163Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently Observing and have been locked for over 6 hours. Pretty quiet shift - we had one lockloss from the wind suddenly picking up, but the ifo was able to relock itself without any issue, even though the winds were above 30mph for the first part of relocking. We also had another superevent candidate come in!
