The Moon and Saturn will make a close approach, passing within a mere 3.2 arcminutes of each other. From some parts of the world, the Moon will pass in front of Saturn, creating a lunar occultation. The Moon will be 23 days old.

From Columbus , the pair will be visible in the dawn sky, rising at 03:43 (EST) – 3 hours and 36 minutes before the Sun – and reaching an altitude of 24° above the south-eastern horizon before fading from view as dawn breaks at around 06:48.

The Moon will be at mag -11.6; and Saturn will be at mag 0.4. Both objects will lie in the constellation Sagittarius.

They will be close enough to fit within the field of view of a telescope, but will also 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 Saturn 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 19h23m50s 21°40'S Sagittarius -11.6 29'46"3
Saturn 19h23m50s 21°37'S Sagittarius 0.4 16"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 78° from the Sun, which is in Pisces 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.
