1 Ceres and Neptune will share the same right ascension, with 1 Ceres passing 9°38' to the north of Neptune.
From South El Monte , the pair will be visible in the evening sky, becoming accessible around 18:14 (PDT), 36° above your eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 22:30, 87° above your southern horizon. They will continue to be observable until around 04:04, when they sink below 21° above your north-western horizon.
1 Ceres will be at mag 7.1, and Neptune at mag 7.8, both in the constellation Gemini.
A graph of the angular separation between 1 Ceres and Neptune 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 |
| 1 Ceres | 07h03m20s | 31°28'N | Gemini | 7.1 | 0"0 |
| Neptune | 07h03m20s | 21°49'N | Gemini | 7.8 | 2"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 156° from the Sun, which is in Capricornus at this time of year.
