Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 55' to the south of Mars. The Moon will be 9 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 19:24 (EST), 19° above your southern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 20:43, 22° above your southern horizon. They will continue to be observable until around 00:03, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.4, and Mars at mag -1.3, 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 19h21m00s 27°22'S Sagittarius -12.4 32'15"2
Mars 19h21m00s 26°27'S Sagittarius -1.3 15"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 117° from the Sun, which is in Leo at this time of year.
