The Moon and Mars will share the same right ascension, with the Moon passing 4°30' to the south of Mars. The Moon will be 2 days old.
From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 0° above the horizon at dusk.
The Moon will be at mag -9.0, and Mars at mag 1.5, both in the constellation Libra.
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.
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 | 15h14m20s | 22°50'S | Libra | -9.0 | 29'23"3 |
| Mars | 15h14m20s | 18°20'S | Libra | 1.5 | 3"9 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 22° from the Sun, which is in Virgo at this time of year.
