The Moon and Neptune will make a close approach, passing within a mere 7.2 arcminutes of each other. The Moon will be 10 days old.
From South El Monte , the pair will become visible at around 21:13 (PDT), 42° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 02:14.
The Moon will be at mag -12.4; and Neptune will be at mag 7.9. Both objects will lie in the constellation Libra.
They will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.
A graph of the angular separation between the Moon and Neptune 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 | 14h31m20s | 12°52'S | Libra | -12.4 | 32'14"3 |
| Neptune | 14h31m10s | 12°59'S | Libra | 7.9 | 2"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 122° from the Sun, which is in Gemini at this time of year.
