Just noticed that the range has been degrading for the last 2 hours or so. Range had drifted down to about 108 mpc, no apparent environmental causes, wind is low, microseism hasn't changed. Following Sheila's instructions in alog 54967. Seems like the range has recovered, but it took several minutes after relocking the squeezer to see that.
