The Moon and Mars will share the same right ascension, with the Moon passing 4°54' to the south of Mars. The Moon will be 10 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 evening sky, becoming accessible around 16:46 (EDT) as the dusk sky fades, 28° above your eastern horizon. They will then reach its highest point in the sky at 20:31, 54° above your southern horizon. They will continue to be observable until around 02:13, when they sink below 7° above your western horizon.

The Moon will be at mag -12.3 in the constellation Cetus, and Mars at mag -1.3 in the neighbouring constellation of Pisces.

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 00h58m40s +01°04' Cetus -12.3 29'28"4
Mars 00h58m40s +05°58' Pisces -1.3 15"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 130° from the Sun, which is in Scorpius at this time of year.
