I was looking at the lockloss sheet and noticed that this weekend, there were three locklosses that were similar to each other. Ryan Short noted one in an alog a couple days ago: 82809.
The locklosses look similar to what we sometimes see when we lose lock due to ground motion from an earthquake or wind, but in all three cases there was no earthquake motion, and the wind was below 20mph. There will be an 11 Hz oscillation starting about 1 second before the lockloss, and it can be seen in DARM, all QUADs, MICH, PRCL, and SRCL.
Lockloss times:
There was another instance of a lockloss that looked just like these on February 7th 2025 at 05:47UTC as well.
Some more of these weird locklosses from the last day:
