Astronomical Ephemerides computes ephemerides for the major objects of the solar system, using an Emscripten port of the AA+ library (version 1.80). More about Emscripten on their site.

Lunar Eclipses


Accuracy of the times displayed below is about 1 minute.

 

Solar Eclipses

To obtain the value of a given Besselian element for a given time T, compute it in the following manner:

    t = T - T0
    A(t) = A0 + t * A1 + t2 * A2 + t3 * A3

where A is any of the elements from the tables below.

The values from the table are valid for a time interval from T0 - 3h to T0 + 3h.

x, y, l1 and l2 are in Earth radii.
μ and d are in sexagesimal degrees (°)
