Briefly Tried Switching Back to 90 [mHz] Blends, uSeism + Wind Still Too Large
J. Kissel, T. Schaffer, S. Dwyer

After loosing lock, "the plan" had been to switch back to 90 [mHz] blend fliters, after having switched to 45 [mHz] over the weekend (see LHO aLOG 22410). After loosing lock at 18:12 UTC, by ~18:30 UTC we had BSC platforms switched to 90 [mHz] blends. Sheila commented that motion is still too large, so we switched back to 45 [mHz] blends by 19:00 UTC, and we're resuming lock acquisition. We'll see how it goes -- the wind is on its way up...

I attach some relevant screenshots of the amplitude of motion over the past 12 hours.
