Seems to be the microseism keeping us down. The DMT monitor is showing levels reaching 0.5um/s. Sheila, Jeff K, Jim W, and I have been trying some different blend combinations and trying to switch from the 45mHz to the 90mHz at DC_READOUT, but just can't seem to make it past that point.  Sheila still has some ideas up her sleeve, so I will update more along the way.
