Alcyone Software

Alcyone Solar Eclipse Calculator (ASEC) 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 (see screenshots). Locations can be selected from an extendable location database with more than 2000 entries. In addition reports of local circumstances of successive solar eclipses at a specified location can be generated (see example).
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.

Exporting maps for import into graphics applications is available as well as printing maps and tables (see example). Different world maps and maps of all continents are included. For the calculation of "historical" eclipses nine different formulas for the determination of DT (TD-UT) are provided.
