The brightest spot in my inspection of HAM5/6 through available viewports was a spot on the septum window seen from 3 degrees (https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=48965). Anamaria does not have a viewport at the 3 degree location and did not see a spot from the viewport at LLO that gives a 28 degree view of the septum window (https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=45980). We looked from 28 degrees at LHO to see if there was a difference between LLO and LHO. Figure 1 shows that a beam spot was visible, suggesting that there is a difference between the two sites.
