The Moon and Jupiter will share the same right ascension, with the Moon passing 50' to the north of Jupiter. The Moon will be 25 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From London , the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will be visible in the dawn sky, rising at 03:53 (BST) – 1 hour and 29 minutes before the Sun – and reaching an altitude of 9° above the eastern horizon before fading from view as dawn breaks at around 04:58.
The Moon will be at mag -10.8, and Jupiter at mag -2.2, both in the constellation Aquarius.
The pair will be a little too widely separated to fit comfortably 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 | 23h21m30s | 4°23'S | Aquarius | -10.8 | 29'38"4 |
| Jupiter | 23h21m30s | 5°14'S | Aquarius | -2.2 | 34"9 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 53° from the Sun, which is in Aries at this time of year.
