The Moon and Mars will share the same right ascension, with the Moon passing 13' to the north of Mars. The Moon will be 15 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Fairfield , the pair will be visible in the morning sky, becoming accessible around 17:32, when they reach an altitude of 7° above your north-eastern horizon. They will then reach their highest point in the sky at 00:19, 73° above your southern horizon. They will be lost to dawn twilight around 06:55, 9° above your north-western horizon.
The Moon will be at mag -12.7, and Mars at mag -1.4, both in the constellation Gemini.
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 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 | 07h58m10s | 25°13'N | Gemini | -12.7 | 31'14"5 |
| Mars | 07h58m10s | 25°00'N | Gemini | -1.4 | 14"5 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Sagittarius at this time of year.
