Winds are starting to come back up. Before I noticed that I saw the ETMX ISI was starting it's slow ring up. Suspecting the lock was not going to last long I briefly took the IFO out of observe, so I could try disabling the boost on the ETMX ST1 X isolation bank, as that had been successful in the past of settling the ISI down (based on one data point, so it may not be true...). This didn't have any effect however, so I've put the boost back on, and gone back to observing. The wind seems to be getting worse, so this lock probably won't make it much longer. Useism is getting better, so we might be able to lock again, if we switch back to 90mhz blends, but the current lock probably wouldn't survive the switch.

I turned the boost off at about 18:34, then back on at about 18:48, UTC.
