The Moon and Jupiter will make a close approach, passing within a mere 56.8 arcminutes of each other. From some parts of the world, the Moon will pass in front of Jupiter, creating a lunar occultation. The Moon will be 12 days old.

From Fairfield , the pair will be visible in the evening sky, becoming accessible around 18:40 (EDT), 19° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 22:01, 37° above your southern horizon. They will continue to be observable until around 02:36, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.6; and Jupiter will be at mag -2.8. Both objects will lie in the constellation Aquarius.

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

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Jupiter around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 22h26m20s 12°13'S Aquarius -12.6 32'51"1
Jupiter 22h25m20s 11°19'S Aquarius -2.8 45"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 136° from the Sun, which is in Virgo at this time of year.
