    I've done my best to follow his arguments, but failed.
    
    I don't see the basis on which he decided to replace an observed zenith
    distance for the Moon of 38 degrees by one of 40 degrees. Where did that
    value of 40 come from?
    
    Perhaps it would help those that are slow on the uptake, such as me, if
    Frank gave a complete numerical example of how it calculates out.
    
    ==========================
    
    And that isn't the only "clearing miracle" that's been giving me trouble,
    recently, as I noted in [5595]. This related back to Jeremy's lunar, which
    has sparked a lot of discussion, which still continues. In that posting, I
    noted that the lunar distance exceeded 85�, so not far from 90�, and added-
    
    "I find it hard to reconcile the effect of the Moon parallax / refraction
    on this observation, stated as being 27.2', with Frank's statement, in
    [5574]-
    "PS: And a reminder: don't fuss over the exact interpolated altitude of the
    Moon. When the lunar distance is close to 90 degrees, the altitude of the
    Moon can be way off and it will not affect the calculation significantly."
    (a point that Frank has made in previous postings)."
    
    The point being that in this case the Moon parallax / refraction correction
    appears to require applying in its entirety to the lunar distance, even
    though the lunar distance is so close to 90 degrees.
    
    Frank claims that near 90�, any error in Moon altitude will cancel out. But 
    how would he work that particular example, to ensure that it did? It relates 
    to an earlier miracle claim by Frank, from over 3 years back.
    
    George.
