Information about the Sun is published in Section C of The Astronomical Almanac.
The data include notes and formulae for: the mean orbital elements; apparent ecliptic coordinates;
times of transit; elements of rotation; and heliographic coordinates. Daily tabulations of ecliptic
and equatorial coordinates, distance, horizontal parallax, semi-diameter and ephemeris transit time
are given. Daily geocentric rectangular coordinates are tabulated for the edition year.
- Synodic rotation numbers
- Ecliptic and equatorial coordinates - daily ephemeris
- Heliographic coordinates, horizontal parallax, semidiameter and time of ephemeris transit
- Geocentric rectangular coordinates - daily ephemeris
- Formulas for Sun's coordinates and the equation of time
