Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 2°15' to the south of Jupiter. The Moon will be 19 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 dawn sky, rising at 00:41 (EST) and reaching an altitude of 27° above the southern horizon before fading from view as dawn breaks at around 05:16.

The Moon will be at mag -12.3, and Jupiter at mag -2.5, both in the constellation Sagittarius.

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 19h56m00s 23°10'S Sagittarius -12.3 30'55"5
Jupiter 19h56m00s 20°55'S Sagittarius -2.5 41"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 115° from the Sun, which is in Aries at this time of year.
