The Moon and Jupiter will make a close approach, passing within 5°24' of each other. The Moon will be 22 days old.
From Fairfield , the pair will be visible in the morning sky, becoming accessible around 00:19, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 05:46, 51° above your southern horizon. They will be lost to dawn twilight around 06:52, 48° above your south-western horizon.
The Moon will be at mag -12.0; and Jupiter will be at mag -2.1. Both objects will lie in the constellation Virgo.
They will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
At around the same time, the pair will also share the same right ascension – called a conjunction.
A graph of the angular separation between the Moon and Jupiter around the time of closest approach is available here.
The positions of the pair at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 11h38m30s | 2°15'S | Virgo | -12.0 | 32'02"3 |
| Jupiter | 11h48m10s | 2°35'N | Virgo | -2.1 | 36"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 91° from the Sun, which is in Sagittarius at this time of year.
