Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 8°11' to the south of Saturn. The Moon will be 9 days old.

From South El Monte , the pair will become visible at around 20:39 (PDT), 53° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 02:15.

The Moon will be at mag -12.3, and Saturn at mag 0.6, both in the constellation Virgo.

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 Saturn 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 12h41m50s 9°53'S Virgo -12.3 32'28"3
Saturn 12h41m50s 1°42'S Virgo 0.6 18"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 113° from the Sun, which is in Taurus at this time of year.
