The Moon and Jupiter will share the same right ascension, with the Moon passing 0°55' to the south of Jupiter. The Moon will be 26 days old.

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

From Seattle, the pair will be visible in the dawn sky, rising at 05:11 (PDT) – 1 hour and 59 minutes before the Sun – and reaching an altitude of 11° above the south-eastern horizon before fading from view as dawn breaks around 06:49.

The Moon will be at mag -10.5, and Jupiter at mag -1.9, both in the constellation Sagittarius.

The pair 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.

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 19h15m00s -23°14' Sagittarius -10.5 30'24"4
Jupiter 19h15m00s -22°18' Sagittarius -1.9 32"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 43° from the Sun, which is in Aquarius 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.
