    Re: V-Correction for Sun? Answer from UKHO...

     Gary,

    My hard copy of the Air Almanac is 1998 and it lists GHA of the sun and Aries and the SHA of the stars to the tenth of a minute.  It also lists the dec. of the sun and stars to the tenth.  The inside front cover has the 4 second interpolation table but on page A 164 and A 165 the table is for every second for ten minutes.

    The only place that the new Air Almanac is less precise than the NA is the Moon and planets - they are listed to whole minutes only.

    As you know, the Air Almanac is not printed anymore but is avaible ( free ) as a PDF download from the USNO website.  Other than the Moon or planets the data is no less than the ( not free ) Nautical Almanac.

    John H.
