Ops Day Shift Summary

TITLE: "10/30 [DAY Shift]: 15:00-23:00UTC (08:00-16:00 PDT), all times posted in UTC"

STATE Of H1: No lock attempt. Too windy to even try.

SUPPORT: Evan, Sheila, Hugh

SHIFT SUMMARY: We've tried to lock for several hours in the morning. The wind speed was higher when the time the ifo lost lock so we decided that it's not going to happen and left the ifo alone for the rest of the shift. Wind speed stays above 40mph for the past 10 hours.

INCOMING OPERATOR: Travis
