Subject: CCW Lock 

 Today I mounted the mode matching lenses on translation stages, and Alastair and I re-aligned the CCW beam into the cavity. We hooked up the PDH servo and brought the beam into lock. Alastair noted that it was staying locked much longer than it ever had before, but of course a slight bump to the table would bring it out of lock  (or back again). I've attached a picture of the monitor output for the locked beam.
