The Moon and Jupiter will share the same right ascension, with the Moon passing 4°19' to the south of Jupiter. The Moon will be 29 days old.
From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 4° above the horizon at dawn.
The Moon will be at mag -7.9, and Jupiter at mag -1.8, 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 | 18h19m00s | 27°31'S | Sagittarius | -7.9 | 30'01"1 |
| Jupiter | 18h19m00s | 23°12'S | Sagittarius | -1.8 | 31"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 12° from the Sun, which is in Sagittarius at this time of year.

Warning
Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
