The Moon and Jupiter will make a close approach, passing within 4°43' of each other. The Moon will be 13 days old.
From South El Monte , the pair will be visible in the evening sky, becoming accessible around 20:27 (PST), 17° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 23:34, 32° above your southern horizon. They will continue to be observable until around 03:42, when they sink below 7° above your south-western horizon.
The Moon will be at mag -12.7; and Jupiter will be at mag -2.6. Both objects will lie in the constellation Sagittarius.
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 Jupiter 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 | 17h48m10s | 18°24'S | Sagittarius | -12.7 | 33'21"3 |
| Jupiter | 17h47m30s | 23°08'S | Sagittarius | -2.6 | 45"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 160° from the Sun, which is in Gemini at this time of year.
