Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 15' to the south of Mars. The Moon will be 23 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Los Angeles , the pair will be visible in the dawn sky, rising at 00:48 (PDT) and reaching an altitude of 57° above the eastern horizon before fading from view as dawn breaks at around 05:36.

The Moon will be at mag -11.4, and Mars at mag 0.6, both in the constellation Taurus.

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 04h25m30s 20°36'N Taurus -11.4 29'31"8
Mars 04h25m30s 20°52'N Taurus 0.6 6"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 72° from the Sun, which is in Leo at this time of year.
