The Moon and Mars will share the same right ascension, with the Moon passing 2°45' to the south of Mars. The Moon will be 22 days old.

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

From Seattle, the pair will be difficult to observe as they will appear no higher than 19° above the horizon. They will be visible in the dawn sky, rising at 02:47 (PST) – 2 hours and 46 minutes before the Sun – and reaching an altitude of 19° above the south-eastern horizon before fading from view as dawn breaks around 05:09.

The Moon will be at mag -11.7, and Mars at mag 0.2, both in the constellation Aquarius.

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 22h15m00s -15°41' Aquarius -11.7 29'53"2
Mars 22h15m00s -12°56' Aquarius 0.2 8"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 84° from the Sun, which is in Taurus at this time of year.
