The Moon and Venus will share the same right ascension, with the Moon passing 6°29' to the north of Venus. The Moon will be 25 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 02:59 (EST) – 3 hours and 49 minutes before the Sun – and reaching an altitude of 37° above the south-eastern horizon before fading from view as dawn breaks at around 06:31.
The Moon will be at mag -10.6, and Venus at mag -4.5, both in the constellation Leo.
The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
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 | 10h09m00s | 16°04'N | Leo | -10.6 | 29'27"6 |
| Venus | 10h09m00s | 9°35'N | Leo | -4.5 | 28"1 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 48° from the Sun, which is in Virgo at this time of year.
