We aligned the PRMI. We definitely can lock MICH, but we're not really sure if PRCL is really being locked or not. I don't think it is.
Anyhow, we found 2 different places on the AS camera that we can align the PRMI. One (middle, right hand side of the camera), we see the same weird fringing that we've been seeing for a week or two. The other (lower left side of the camera), we see different fringing, almost reminds me more of back in the day a few months ago when the beam looked like it was expanding on each pass. As I type, Evan is uploading the movies to youtube. I *still* don't know how to embed youtube videos on the elog!
Also, we found both forward-going and backward-going POP beams coming out onto the POX table. We placed the 2" lens in the path of the backwards beam, so that we can find it again. We can't see it on an IR card, but if we put some foil where we think the beam should be, we can use a viewer to see the spot on the foil. Poking a hole in the foil made an impromptu iris.
