The Moon and Jupiter will make a close approach, passing within 2°33' of each other.
From London (click to change), the pair will be visible in the morning sky. They will become accessible at around 01:02, when they rise 7° above your eastern horizon. They will then reach its highest point in the sky at 05:30, 31° above your southern horizon. They will be lost to dawn twilight at around 07:30, 25° above your south-western horizon.
At the moment of closest approach, the Moon will be at mag -12.0, and Jupiter at mag -2.1, both in the constellation Virgo.
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.
The precise positions of the Moon and Jupiter at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 13h28m00s | -05°01' | Virgo | -12.0 | 29'50"5 |
| Jupiter | 13h24m50s | -07°27' | Virgo | -2.1 | 36"7 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 96° from the Sun, which is in Sagittarius at this time of year.
