TITLE: 09/26 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY: Currently relocking and in LASER_NOISE_SUPPRESSION. One lockloss today due to the wind, and relocking has been taking a while because of the wind. We were worried about the ETMY Roll mode earlier, but it ended up coming back down on its own. Maybe we should keep an eye on it over the weekend, but it seemed like the current setting are doing okay. The ion pump is still running in the LVEA - since the lockloss was so late in the evening, there were no vacuum people on site to turn it off, but that's okay.
