Lunar Eclipse Predictions with JPL DE406

Fred Espenak

The coordinates of the Sun and Moon used in these eclipse predictions have been calculated on the basis of the JPL DE406 solar system ephemeris. This ephemeris consists of computer representations of the positions, velocities and accelerations of major Solar System bodies, tabulated at equally spaced intervals of time, covering the span -3001 Feb 04 to +3000 May 06. DE406 is a slightly less accurate version of the DE405 but it covers a much longer time span. The interpolating accuracy of the DE406 is no worse than 25 meters for any planet and no worse than 1 meter for the Moon. See Jet Propulsion Laboratory Developmental Ephemeris for more information of these ephemerides.
