TITLE: 12/26 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: We are Observing and have now been Locked for 14.5 hours.

Very quiet shift, with the only thing happening was that ITMY Mode 20 (aka narrower ITMY Mode 6) had started ringing back up slowly. It seems like during the first two hours that we had been locked, the ITMY 5 gain setting had helped ITMY20 settle down to around 4.06, and then over the next four hours ITMY20 continued decreasing at a lower rate of change from 4.06 -> 3.99. However, after this, ITMY20 started slowly ringing back up, and 4.5hours later was back to being above 4.06. During all of this, ITMY 5, 6, and 10 were still decreasing. I decided to try turning the ITMY5 gain to 0 to see what that would do, but that caused mode 5 to immediately start rising at a much faster rate than mode 20 had been before, so I turned the gain back on and they've all been decreasing again the past 3.5 hours.
