Planetary Conjunctions:

The following were calculated with various incarnations of my conjunction program.

These are geocentric conjunctions (run on a UNIX system in 2003).

• 2-planet in RA (1988-2037)
• 2-planet in Celestial Longitude (1988-2037)

These are geocentric conjunctions in celestial longitude (VAX version run around 1994).

• 2-planet (1974-2068)
• Venus-Jupiter (1991-2220)
• 2-planet closer than 0.1 degree (1967-1578)
• Jupiter-Saturn (1981-205 B.C.)

These are three-planet conjunctions when the planets fit in the smallest circle.

• Triple Conjunctions (1971-2029)
• Triple Conjunctions (1959-2056) [New run in 2006]

Additional information is found in "Mutual Occultations of Planets: 1557-2230", Sky and Telescope, March 1979.
