    Re: Nautical Almanac Sun Altitude Correction Question
    From: Trevor Kenchington
    Date: 2005 Jan 25, 12:24 -0400

    Have a look in the list archives for April 20, 2004. A notice was posted
    explaining that the refraction values had been recalculated, with effect
    from the 2004 almanac.
