The Moon and Saturn will make a close approach, passing within a mere 33.5 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 24 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 01:50 (EDT) and reaching an altitude of 32° above the southern horizon before fading from view as dawn breaks at around 06:35.

The Moon will be at mag -11.6; and Saturn will be at mag 0.3. Both objects will lie in the constellation Libra.

They 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.

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 15h20m20s 16°39'S Libra -11.6 31'49"4
Saturn 15h20m40s 16°06'S Libra 0.3 16"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 73° from the Sun, which is in Capricornus at this time of year.
