The Moon and Saturn will make a close approach, passing within 1°38' of each other.
From London (click to change), the pair will be difficult to observe as they will appear no higher than 16° above the horizon. They will be visible in the morning sky. They will become accessible at around 00:12, when they rise 7° above your south-eastern horizon. They will then reach its highest point in the sky at 02:54, 16° above your southern horizon. They will be lost to dawn twilight at around 04:19, 13° above your southern horizon.
At the moment of closest approach, the Moon will be at mag -12.4, and Saturn at mag 0.9, 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.
The precise positions of the Moon and Saturn at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 18h32m10s | -20°42' | Sagittarius | -12.4 | 29'33"3 |
| Saturn | 18h32m10s | -22°21' | Sagittarius | 0.9 | 18"1 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 152° from the Sun, which is in Taurus at this time of year.
