Looking down the tube from the O1, I didn't see any spill caused by an edge being illuminated. I think I recall seeing this reflection before and I recall not being able to do much about it. The image on the occulter, though does not look centered.

Spar flexure may have shifted. N/S stepper still at a limit, limit rod is pushed toward spar, I did not notice if it was being pushed the other way earlier. N/S image symmetry is much better now. MKIII COMMENT: Sun Jun 15 21:51:14 GMT 1997 I had to touch up DPMON pointing in N/S direction although not by much and a lot later on. Problem may not be spar flexure related.
