Microwaves are back on at 69.97 GHz and polarization is at 29.4%.

At the end of the dilution, the helium level in the nose was about 70%. The updated procedure in the Wiki was followed to control the cryo levels before turning the microwaves on, but the nose skyrocketed to ~98% and didn't want to come down. To keep it from overfilling and breaking the readout, PID control was taken off auto and set to 0 until the level hit about 50%, then manually set back to 0.6 and returned to PID control.

The black line on the attached graph shows how the nose level changed. It is now stable around 50%.
