TITLE: 09/25 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 147Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY: H1 has been locked the whole day so far; current lock stretch is up to almost 11.5 hours. The ETMY roll mode is slightly more rung up than it has been in the past few days, but maybe not egregiously so; Oli will keep an eye on it this evening. Other than commissioning time this morning, it's been a quiet shift.
