The Moon and Jupiter will share the same right ascension, with the Moon passing 1°48' to the south of Jupiter. The Moon will be 15 days old.

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

From San Diego , the pair will be visible in the morning sky, becoming accessible around 20:25, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 01:49, 57° above your southern horizon. They will be lost to dawn twilight around 06:12, 20° above your western horizon.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -12.7, and Jupiter at mag -2.9, both in the constellation Pisces.

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 Jupiter 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 00h22m10s 1°09'S Pisces -12.7 31'55"3
Jupiter 00h22m10s 0°39'N Pisces -2.9 48"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 163° from the Sun, which is in Leo at this time of year.
