The Moon and Saturn will share the same right ascension, with the Moon passing 3°49' to the south of Saturn. The Moon will be 2 days old.

From San Diego , the pair will be visible from soon after it rises, at 08:05, until soon before it sets at 18:54. Always take extreme caution when trying to make daytime observations of the Moon while the Sun is above the horizon.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -9.2, and Saturn at mag 0.7, both in the constellation Capricornus.

The pair 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.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 21h48m50s 18°20'S Capricornus -9.2 33'18"1
Saturn 21h48m50s 14°31'S Capricornus 0.7 15"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 21° from the Sun, which is in Capricornus at this time of year.
