The Moon and Jupiter will share the same right ascension, with the Moon passing 4°08' to the south of Jupiter. The Moon will be 9 days old.

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

From Fairfield, the pair will be visible in the evening sky, becoming accessible around 18:31 (EDT) as the dusk sky fades, 24° above your south-eastern horizon. They will then reach their highest point in the sky at 20:56, 33° above your southern horizon. They will continue to be observable until around 01:14, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.3, and Jupiter at mag -2.6, both in the constellation Capricornus.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

A graph of the angular separation between the Moon and Jupiter 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
The Moon 21h39m10s -19°23' Capricornus -12.3 31'14"9
Jupiter 21h39m10s -15°15' Capricornus -2.6 43"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 118° from the Sun, which is in Virgo at this time of year.
