The Moon and Saturn will share the same right ascension, with the Moon passing 21' to the north of Saturn. The Moon will be 6 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Seattle , the pair will be visible from soon after it rises, at 12:38, until soon before it sets at 22:27.
The Moon will be at mag -11.4, and Saturn at mag 0.4, both in the constellation Libra.
The pair will be close enough to fit within the field of view of a telescope, but will also 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 | 15h03m50s | 14°46'S | Libra | -11.4 | 30'46"1 |
| Saturn | 15h03m50s | 15°07'S | Libra | 0.4 | 16"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 69° from the Sun, which is in Leo at this time of year.
