Planetary Aspects and Transits 26.1Click on the title for the full description. |

This is a program to calculate geocentric aspects between planets at a given date. Also displays personal transits for a given birthdate, and synastry for two birthdates. It identifies aspect patterns (such as grand trines and yods) and supports searching for occurrences of them. It has graphical and dynamical displays (as well as tabular) which show how transits change over time, and how the position of a transiting planet changes. It supports both tropical and sidereal zodiacs. Read more ... |

This is a heliocentric version of Planetary Aspects and Transits, and does everything that that program does (except, of course, that the Moon is not included). In addition, when searching for the occurrence of a particular aspect pattern you can ask it to search for an aspect pattern involving up to three specified planets (e.g. a grand trine involving Earth and Pluto).

Unlike the programs above, PSEA is not concerned with planetary transits, rather it displays, for a date or a range of dates, the times of exact geocentric aspects between planets, stars and the Moon. It also calculates declinations at those times. Read more ... |
