Alcyone Astronomical Software - ephemeris software, astronomical tables, solar eclipse calculator
This website provides astronomical software: Alcyone Ephemeris - an accurate and fast astronomical ephemeris calculator covering the period 3000 BC to AD 3000. It calculates heliocentric, geocentric, and topocentric ephemeris data of the Sun (Earth), planets, 18 natural satellites, and small bodies (minor planets and comets) in ecliptical, equatorial, and horizontal coordinates, with optional corrections for parallax and refraction; rectangular coordinates, velocity, apparent diameter, magnitude, phase, lunar libration, and more. In addition Alcyone Ephemeris offers a wealth of functionality: star chart generation, 3D-visualization of heliocentric and planetocentric orbits, plotting ephemeris data (as a function of time or in a parametric plot), searching for specific values, ephemeris data export (Excel, HTML, XML, Text), scripting to write programs for more complex computations, and printing. Access to the complete Bright Star Catalogue, a calendar conversion tool, and an astronomical event calculator are available.
The ephemeris calculation is based upon Steve Moshier's analytical ephemeris using trigonometric expansions for the earth and planets and the lunar ephemeris ELP2000-85 of Chapront-Touzé and Chapront for the moon, both adjusted to Jet Propulsion Laboratory's DE404. There are further adjustments in Alcyone Ephemeris to JPL's more recent DE406, the most accurate long-term ephemeris
Alcyone Solar Eclipse Calculator - calculates the local circumstances of all solar eclipses that occur(ed) in the time range between -1999 (2000 B.C) and AD 3000. The local circumstances are presented as eclipse maps and tables for a list of locations. Alcyone Solar Eclipse Calculator can be used as a 'stand-alone application' or as an addition to Alcyone Ephemeris. The calculation of the local circumstances of solar eclipses is based upon the data from the Five Millenium Canon of Solar Eclipses -1999 to 3000 (Fred Espenak, NASA's GSFC) with Besselian Elements provided by Jean Meuus. Alcyone Astronomical Tables - a collection of astronomical data in electronic form. It provides detailed information on various astronomical phenomena (conjunctions with the Sun, planetary conjunctions, oppositions, stations, greatest eleongations, lunar phases, equinoxes and solstices, passages of aphelia and perihelia, solar and lunar eclipses) covering the period 3000 BC (2000 BC) to AD 3000. Alcyone Astrononomical Tables can be used as a 'stand-alone program' or as an addition to Alcyone Ephemeris.
