The Moon and Mars will share the same right ascension, with the Moon passing 5°38' to the north of Mars. The Moon will be 5 days old.

From Fairfield, the pair will be difficult to observe as they will appear no higher than 19° above the horizon. They will become visible around 18:56 (EST) as the dusk sky fades, 19° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 51 minutes after the Sun at 21:29.

The Moon will be at mag -11.3, and Mars at mag 0.8, both in the constellation Ophiuchus.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 16h34m50s -17°51' Ophiuchus -11.3 31'12"9
Mars 16h34m50s -23°30' Ophiuchus 0.8 6"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 63° from the Sun, which is in Virgo at this time of year.
