    In his report, Brad commented on his 96632A / 96132 observations: "After
    returning from drawing field, I may have switched over to 27954, which was
    nearby, but noticeably off track. Perhaps someone can check to see which was
    which?". It appears to me that all of his 96632A are in fact 27954, but I agree,
    it does seem off-track.
    
    As part of my analysis, I produced alternative solutions, which cover fairly
    long arcs of earlier confirmed observations (the first one is more recent):
