The Moon and Mars will share the same right ascension, with the Moon passing 4°38' to the south of Mars. The Moon will be 23 days old.
From Cambridge, the pair will be visible in the morning sky, becoming accessible around 00:52, when they rise to an altitude of 7° above your eastern horizon. They will then reach its highest point in the sky at 06:03, 46° above your southern horizon. They will be lost to dawn twilight around 06:53, 44° above your southern horizon.
The Moon will be at mag -11.8, and Mars at mag 0.9, both in the constellation Virgo.
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 Sagittarius at this time of year.

The circumstances of this event were computed using the DE405 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.
