Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 15' to the south of Saturn. The Moon will be 6 days old.

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

From Fairfield , the pair will become visible at around 20:44 (EDT), 28° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 46 minutes after the Sun at 23:54.

The Moon will be at mag -11.9, and Saturn at mag 0.4, both in the constellation Libra.

The pair 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.

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 14h34m30s 12°58'S Libra -11.9 31'58"2
Saturn 14h34m30s 12°43'S Libra 0.4 16"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 88° from the Sun, which is in Cancer at this time of year.
