MICA Version 2.0 tabulates several types of conjunctions for a range of dates. A solar conjunction occurs when the Sun and another celestial body (planet and/or asteroid) have the same apparent geocentric longitude. A Lunar conjunction or a planetary conjunction occurs when the two celestial bodies have the same apparent geocentric right ascension. MICA tabulates the following conjunctions:

  • The Sun with the major planets and/or selected asteroids.
  • The Moon with the major planets, selected asteroids and/or selected bright stars.
  • A major planet with the other major planet, selected asteroids and selected bright stars.

The bright stars included in the MICA conjunction tabulations are Aldebaran, Antares, Pollux, Regulus, and Spica. The times and dates of the conjunctions are tabulated, in addition to the apparent geocentric right ascension and the separation, in degrees.
