The Moon and Jupiter will share the same right ascension, with the Moon passing 2°06' to the north of Jupiter. The Moon will be 20 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 morning sky, becoming accessible around 01:44, when they reach an altitude of 7° above your south-eastern horizon. They will then reach their highest point in the sky at 05:25, 25° above your southern horizon. They will be lost to dawn twilight around 05:59, 25° above your southern horizon.
The Moon will be at mag -12.4, and Jupiter at mag -2.3, 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 | 17h53m30s | 20°47'S | Sagittarius | -12.4 | 32'25"3 |
| Jupiter | 17h53m30s | 22°53'S | Sagittarius | -2.3 | 40"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 113° from the Sun, which is in Pisces at this time of year.
