The Moon and Mars will share the same right ascension, with the Moon passing 0°45' to the north of Mars. The Moon will be 25 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 difficult to observe as they will appear no higher than 19° above the horizon. They will be visible in the dawn sky, rising at 03:29 (EDT) – 3 hours and 9 minutes before the Sun – and reaching an altitude of 19° above the south-eastern horizon before fading from view as dawn breaks around 06:19.

The Moon will be at mag -11.1, and Mars at mag 1.2, both in the constellation Sagittarius.

The pair will be a little too widely separated to fit comfortably 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 Mars 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 18h05m00s -22°54' Sagittarius -11.1 30'47"3
Mars 18h05m00s -23°39' Sagittarius 1.2 5"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 57° from the Sun, which is in Aquarius at this time of year.
