The Moon and Saturn will make a close approach, passing within a mere 36.9 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 18 days old.

From Columbus , the pair will be visible in the morning sky, becoming accessible around 20:10, when they reach an altitude of 9° above your eastern horizon. They will then reach their highest point in the sky at 02:31, 70° above your southern horizon. They will be lost to dawn twilight around 06:38, 34° above your western horizon.

The Moon will be at mag -12.6; and Saturn will be at mag -0.4. Both objects will lie in the constellation Taurus.

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 04h49m40s 21°10'N Taurus -12.6 31'06"9
Saturn 04h50m10s 20°34'N Taurus -0.4 20"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 147° from the Sun, which is in Libra at this time of year.
