The Moon, Saturn and Neptune will make a close approach, passing within 3°30' of each other. The Moon will be 16 days old.
From Fairfield , the trio will be visible in the morning sky, becoming accessible around 20:53, when they reach an altitude of 11° above your eastern horizon. They will then reach their highest point in the sky at 01:43, 46° above your southern horizon. They will be lost to dawn twilight around 05:49, 19° above your western horizon.
The Moon will be at mag -12.7; Saturn will be at mag 0.6; and Neptune will be at mag 7.8. The trio will lie in the constellation Pisces.
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 trio 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 trio at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 23h53m50s | 0°25'N | Pisces | -12.7 | 32'33"3 |
| Saturn | 00h00m40s | 2°38'S | Pisces | 0.6 | 19"3 |
| Neptune | 00h05m10s | 0°56'S | Pisces | 7.8 | 2"3 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 167° from the Sun, which is in Leo at this time of year.
