The Moon and Mercury will share the same right ascension, with the Moon passing 25' to the north of Mercury. The Moon will be 2 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From South El Monte , the pair will become visible at around 20:29 (PDT), 13° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 46 minutes after the Sun at 21:45.
The Moon will be at mag -9.2, and Mercury at mag 0.1, both in the constellation Gemini.
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 Mercury 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 | 06h38m50s | 25°22'N | Gemini | -9.2 | 31'34"8 |
| Mercury | 06h38m50s | 24°57'N | Gemini | 0.1 | 7"4 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Taurus at this time of year.
