I'm not sure what is different after maintenance than before, but the 120 Hz jitter peak seems much worse this afternoon than we'd been having.  The wind that has been picking up seems to be exacerbating this more than it has the last few times we had moderate wind.

When we have our commissioning period tomorrow, I'll have a look to see if any cleaning will help.  But, we should also take a look in the morning to see if there are any other alignment changes that happened, or if any of our (quite small list of) maintenance activities could explain this evening's differences.
