The Moon and Saturn will make a close approach, passing within a mere 19.2 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 11 days old.

From Fairfield , the pair will be visible in the evening sky, becoming accessible around 19:24 (EDT), 47° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 21:06, 54° above your southern horizon. They will continue to be observable until around 02:26, when they sink below 11° above your western horizon.

The Moon will be at mag -12.3; and Saturn will be at mag 0.7. Both objects will lie in the constellation Leo.

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 11h30m20s 5°25'N Leo -12.3 29'26"8
Saturn 11h30m50s 5°43'N Leo 0.7 19"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 134° from the Sun, which is in Aries at this time of year.
