  • Page B30, Reduction of Celestial Coordinates:

    replace, entire section “Reduction for nutation — rigorous formulae,”
    with a corrected version of the section

  • Pages B32-B39, table of Nutation, Obliquity & Intermediate System:

    insert 245 under 0h TT in the column headed Julian Date on each page

  • Page B56, Approximate formulae for the pole of the Celestial Intermediate Reference System:

    replace L = 297.5° + 0.996d with L = 279.5° + 0.986d

  • Page B57, Table containing the terms for the Series Parts of s and the Equation of the Equinoxes, fourth column headed “Coefficient C'k for EqE:”

    replace, all plus (+) signs, with minus (-) signs
    replace, all minus (-) signs, with plus (+) signs

    The correct version of the table is provided for clarification

  • Page B67, Step B, line 11:

    replace “longitude of the Earth” with “ecliptic longitude of the Sun”

The Sun, Section C

  • Page C1, Eccentricity of the Sun:

    replace 0.016 683 38 - 0.000 000 0116 d
    with 0.016 706 11 - 0.000 000 0012 d

  • Page C1, Reference to osculating elements of the Earth/Moon barycenter:

    replace pages E3-E4 with pages E5-E6

The Moon, Section D

  • Page D2, Mean inclination of the lunar orbit to the ecliptic:

    replace 5.145 3964 with 5.156 6898

Major Planets, Section E
