The Moon, Jupiter and Mars will make a close approach, passing within 5°15' of each other. The Moon will be 24 days old.
From South El Monte , the trio will be visible in the dawn sky, rising at 02:34 (PDT) – 3 hours and 7 minutes before the Sun – and reaching an altitude of 33° above the eastern horizon before fading from view as dawn breaks at around 05:23.
The Moon will be at mag -11.1; Jupiter will be at mag -2.1; and Mars will be at mag 0.7. The trio will lie in the constellation Pisces.
They will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
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 Jupiter 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 | 00h35m00s | 8°10'N | Pisces | -11.1 | 29'47"4 |
| Jupiter | 00h46m40s | 3°48'N | Pisces | -2.1 | 33"5 |
| Mars | 00h42m40s | 2°47'N | Pisces | 0.7 | 6"1 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 62° from the Sun, which is in Taurus at this time of year.
