We lost lock, and took that as a chance to go back to our SR3/SR2 alignments from before April 23rd.  The attached screenshots are of the AS camera once we went back to the old alignment, and then after we moved SR2 to center the beam on AS_C.  You can see that the beam has fringes when centered on AS_C. 

In order to center on AS_C we had to move -54 urad in pitch, (which would move the beam on SRM upwards), and -27 urad in yaw (moving the beam in the -X direction on SRM)

This is a larger shift than what is suggested by Jenne's look at times when we ran AS_C centering in 77690 .
