The Moon and Mercury will share the same right ascension, with the Moon passing 17' to the south of Mercury. The Moon will be 1 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Cambridge however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 5° above the horizon at dusk.
The Moon will be at mag -8.0, and Mercury at mag -0.9, both in the constellation Capricornus.
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 Mercury 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 | 20h19m50s | 21°52'S | Capricornus | -8.0 | 30'34"8 |
| Mercury | 20h19m50s | 21°35'S | Capricornus | -0.9 | 5"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 13° 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.
