These eclipse predictions were computed by the author based on the DE405 planetary ephemeris computed by the Jet Propulsion Laboratory (JPL). The position of the Sun, Earth and Moon were extracted from the DE405 files using EphemerisCompute, which was written by the author and is freely available for download.

They assume that the Earth and Moon are both ellipsoids with fixed polar and equatorial radii, and do not take into account the irregular topography of either body. All eclipse predictions are made at sea level. In practice, this means that the predictions presented here are inaccurate by at most of few seconds.
