Jupiter and Saturn will share the same right ascension, with Jupiter passing 0°06' to the south of Saturn.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield, the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will become visible around 16:46 (EST) as the dusk sky fades, 17° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 23 minutes after the Sun at 18:48.

Jupiter will be at mag -2.0, and Saturn at mag 0.5, both in the constellation Capricornus.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.

A graph of the angular separation between Jupiter and Saturn around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Jupiter 20h09m40s -20°34' Capricornus -2.0 32"5
Saturn 20h09m40s -20°28' Capricornus 0.5 15"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 30° from the Sun, which is in Sagittarius at this time of year.
