This morning we were struggling to get the baffle alignment scripts to run, complaining that the PZT trigger was off. Sheila looked and we only had light on one of the green in vac QPDs, so she and I went down to the table to investigate. The light going through the two irises before the periscope were slightly off center. We first tried moving ALS M9 (table layout) to better center on the iris and get light on QPD B, this didn't really work. Sheila then moved ALS M11 in +pitch by between 1/16-1/8 of a turn and this restored the light on QPD B. 

I did my best to take some pictures of where the beam now sits in relation to the two irises, but it's tough to tell as the image is blown out.
