The Moon and Mars will share the same right ascension, with the Moon passing 2°17' to the north of Mars. The Moon will be 7 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From San Diego however, the pair will be visible from soon after it rises, at 11:14, until soon before it sets at 01:43.
The Moon will be at mag -11.7, and Mars at mag 0.9, both in the constellation Gemini.
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 coordinates above are given in J2000.0. The pair will be at an angular separation of 83° from the Sun, which is in Pisces at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
