    Error in Nautical Almanac Polaris SHA Feb-June?
    From: Jim Thompson
    Date: 2004 Apr 17, 07:48 -0300

    I am writing up my (finally successful) Polaris sight for my course -- the
    final course element short of the sitdown exam next week.  I have to show
    the position of Polaris on the time diagram.  For that I need the SHA of
    Polaris.  The 2004 Nautical Almanc gives the SHA of Polaris (Ursae Minoris)
    as 320 degrees and 68.6-84.6 minutes.  Surely this is a rare printing error,
    since the minutes portion cannot exceed 60'?
    
    US Navy website: GHA 158d 39.6'
    Henning's website: GHA 158d 39.6', SHA 321d 25.0'
    
    I cannot find an "erratum" page for the Almanac using google.  Thanks.
