The Moon and Saturn will share the same right ascension, with the Moon passing 2°59' to the north of Saturn. The Moon will be 3 days old.
From South El Monte , the pair will be difficult to observe as they will appear no higher than 12° above the horizon. They will become visible at around 17:16 (PDT), 12° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 49 minutes after the Sun at 18:34.
The Moon will be at mag -9.5, and Saturn at mag 0.4, 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 Saturn 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 | 17h44m20s | 19°26'S | Sagittarius | -9.5 | 29'25"5 |
| Saturn | 17h44m20s | 22°26'S | Sagittarius | 0.4 | 15"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Libra at this time of year.
