beam changes on CW1

There are some changes to the beams on Calcite Wedge 1, seen on the analog camera.  Images attached show that the stray beam on the right side of the image was round on 30 Sept. 2019, and now has a tapered side.  Under the beam there are now vertical lines of IR light, where none were before.
