![]() Times of conjunctions, elongations, and oppositions can be calculated accurately using the chapter on Planetary Phenomena. For comet and minor planet watchers, there are chapters on Elliptic, Parabolic and Near Parabolic Motion. Mathematically useful chapters include Interpolation, Curve Fitting, Iteration and Sorting. There are practical chapters on Julian Dates, Sidereal Time, Dynamical Time, Rising and Setting, Coordinate Transformations, Equinoxes and Solstices, and Refraction. The author systematically steps us through each method with real examples. ![]() The Galilean satellites of Jupiter are located with Lieske's E2x3 theory. Chapront's ELP-2000/82 theory provides Lunar positioning. Planetary positioning, including the Sun, is provided by the principal elements of Bretagnon and Francou's VSP087 theory. His chapters on the primary corrections of precession, nutation, parallax, and aberration are thorough and presented in both the equatorial and ecliptic coordinate systems. He brings us into the 21st century with the new J2000.0 epoch and FK5 system. Once again author Jean Meeus demonstrates his expertise in astronomical positioning and applied mathematics with Astronomical Algorithms.
