The Moon and Saturn will make a close approach, passing within 2°26' of each other. The Moon will be 22 days old.

From Seattle, the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will be visible in the dawn sky, rising at 03:17 (PDT) – 3 hours and 3 minutes before the Sun – and reaching an altitude of 17° above the south-eastern horizon before fading from view as dawn breaks around 05:58.

The Moon will be at mag -11.7; and Saturn will be at mag 0.4. Both objects will lie in the constellation Capricornus.

They will be too widely separated to fit 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 20h15m00s -22°23' Capricornus -11.7 30'24"1
Saturn 20h13m30s -19°58' Capricornus 0.4 16"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 84° from the Sun, which is in Pisces at this time of year.
