The Moon and Saturn will share the same right ascension, with the Moon passing 6°24' to the south of Saturn. The Moon will be 5 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 become visible at around 19:12 (EDT), 22° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 25 minutes after the Sun at 22:07.
The Moon will be at mag -11.5, and Saturn at mag 0.3, both in the constellation Ophiuchus.
The pair 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.
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 | 16h59m40s | 27°49'S | Ophiuchus | -11.5 | 31'47"3 |
| Saturn | 16h59m40s | 21°25'S | Ophiuchus | 0.3 | 16"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 71° from the Sun, which is in Virgo at this time of year.
