    Samuel,

    The Additional Correction shown in the Nautical Almanac for Mars is different from year to year, and in fact, actually changes from day to day, but not significantly.

    FYI, here is the 2014 Nautical Almanac Additional Correction for Mars:

      Jan. 1 - Feb. 9
    June 30 - Dec. 31
         0º
        +0.1'
        60º

    Feb. 10 - June 29
        0º
        +0.2'
        41º
          0.1'
        76º

    Stan

    Does the parallax value for Mars change from year to year?
    The copy of the Altitude Correction Tables I have are dated 2003 and list the App. Alt. correction for Mars (on this general date) to be +0.2min for an Ha of less than 40d. So do I assume correctly that they are different each year?
