We seem to have a problem with our yaw ASC at 1.88 Hz.  In several of our recent long locks we have had motion at 1.88 Hz in several of our ASC loops, and this occasionally causes locklosses.  This caused a lockloss the first time we locked after todays earthquakes.

Keita looked at that lockloss, and saw that it shows up much more in ITMY than in the rest of the oplevs. 

In the lockloss plot, it looks like the SOFT loops are ringing up, but this might be misleading because the signals are more quiet than other ASC signals.

Operators:

Over the first half hour or so after we increase power, the recycling gain continues to increase.  It might be that we can only transition from POP WFS to REFL WFS after this has happened. 

If you need to relock tonight, you can try runing through the gaurdian as is.  If that doesn't work, I'd recomend waiting about a half hour at noise tunnings before switching over to REFL WFS and closing the beam diverters.
