    Re: (Fwd) The Most Anomalous Refraction Yet or What ?

    Jim,
    
    thanks, for the moment I'll try to get my head around the approximation. I
    am also going through your posting on this subject of a few weeks ago, which
    you furnished with diagrams.

    The equation I developed in my Navigation paper for the time difference
    between maximum altitude and meridian passage is exact. The simplified
    version for the sun is essentially identical to that in the Admiralty
    Navigation Manual, and has variables of Latitude, Declination and the
    northerly component of speed.
