The Moon and Jupiter will share the same right ascension, with the Moon passing 4°02' to the south of Jupiter. The Moon will be 27 days old.

From Fairfield, the pair will be difficult to observe as they will appear no higher than 8° above the horizon. They will be visible in the dawn sky, rising at 04:58 (EST) – 1 hour and 15 minutes before the Sun – and reaching an altitude of 8° above the south-eastern horizon before fading from view as dawn breaks around 05:55.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -9.9, and Jupiter at mag -2.0, 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 21h24m20s -19°53' Capricornus -9.9 30'51"6
Jupiter 21h24m20s -15°51' Capricornus -2.0 32"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 33° from the Sun, which is in Aquarius at this time of year.
