The Moon and Saturn will share the same right ascension, with the Moon passing 26' to the south of Saturn. The Moon will be 16 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Cambridge , the pair will be visible in the morning sky, becoming accessible around 22:53, when they reach an altitude of 10° above your south-eastern horizon. They will then reach their highest point in the sky at 02:19, 25° above your southern horizon. They will be lost to dawn twilight around 04:28, 19° above your south-western horizon.
The Moon will be at mag -12.5, and Saturn at mag 0.1, both in the constellation Sagittarius.
The pair will be close enough to fit within the field of view of a telescope, but will also 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 | 19h19m30s | 22°16'S | Sagittarius | -12.5 | 30'09"1 |
| Saturn | 19h19m30s | 21°49'S | Sagittarius | 0.1 | 18"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 158° from the Sun, which is in Taurus at this time of year.
