Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 5°00' to the south of Jupiter. The Moon will be 27 days old.

From South El Monte , the pair will be visible in the dawn sky, rising at 04:11 (PDT) – 2 hours and 26 minutes before the Sun – and reaching an altitude of 26° above the eastern horizon before fading from view as dawn breaks at around 06:21.

The Moon will be at mag -9.7 in the constellation Sextans, and Jupiter at mag -1.8 in the neighbouring constellation of Leo.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 10h45m40s 3°49'N Sextans -9.7 30'43"4
Jupiter 10h45m40s 8°49'N Leo -1.8 31"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 29° from the Sun, which is in Virgo at this time of year.
