The Moon and Venus will share the same right ascension, with the Moon passing 2°43' to the south of Venus. The Moon will be 26 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Cambridge , the pair will be visible in the dawn sky, rising at 02:30 (EST) – 2 hours and 53 minutes before the Sun – and reaching an altitude of 26° above the eastern horizon before fading from view as dawn breaks at around 05:02.
The Moon will be at mag -10.5, and Venus at mag -4.0, both in the constellation Taurus.
The pair 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.
A graph of the angular separation between the Moon and Venus 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 | 05h04m20s | 17°58'N | Taurus | -10.5 | 32'57"2 |
| Venus | 05h04m20s | 20°42'N | Taurus | -4.0 | 15"6 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 41° from the Sun, which is in Gemini at this time of year.
