The Moon and Saturn will make a close approach, passing within 2°29' of each other. The Moon will be 7 days old.

From South El Monte , the pair will be visible in the evening sky, becoming accessible around 17:08 (PDT), 45° above your southern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 17:49, 46° above your southern horizon. They will continue to be observable until around 22:26, when they sink below 11° above your western horizon.

The Moon will be at mag -11.9; and Saturn will be at mag 0.7. Both objects will lie in the constellation Aquarius.

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 22h53m00s 11°57'S Aquarius -11.9 30'38"6
Saturn 22h48m40s 9°42'S Aquarius 0.7 17"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 90° from the Sun, which is in Ophiuchus at this time of year.
