The IO Faraday Isolator Forward Rejected Beam is missing it's steering mirror, and dumping a beam on the front of AOE2 and on the frint of the IO beam dump.

In the first image, the top image is the camera view with no IR light, showing the AOE2 baffle, ROM RH11, the steering mirror for the IO faraday forward rejected beam (IO FI FRB), and the beam dump for the IO FI FRB. The bottom image is from today, H1 in NLN at 37W, showing a halo around the AOE2 aperture and a bright beam, which is part of the IO FI FRB.  Part of the IO FI FRB is hitting ROM RH11, and landing on the front of the beam dump, this means that part of the beam is also scattering from the barrel of ROM RH11.

The additional images show these components on HAM2 with IR light, and visible light, and include a diagram of where the IO FI FRB is intended to go.

There is a chance that this could be resolved with changing the alignment of IM3, however, it's equally likely that the angle of the main beam through the IO Faraday is contributing to this issue, and a combination of IM2 and IM3 may be needed to steer the FRB back into the beam dump.  It's also possible that IM1, IM2 and IM3 will need to be adjusted to steer the beam back into the beam dump and also restore the pointing of the main beam into the interferometor, as much as possible.
