The Moon and Jupiter will make a close approach, passing within 2°08' of each other.

From London (click to change), the pair will be visible in the dawn sky. They will rise at 01:41 (GMT), 5 hours and 22 minutes before the Sun, and attain an altitude of 40° above the south-eastern horizon before fading from view as dawn breaks at around 06:39.

At the moment of closest approach, the Moon will be at mag -10.9, and Jupiter at mag -1.9, both in the constellation Leo.

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 11h12m40s +03°51' Leo -10.9 29'30"0
Jupiter 11h15m20s +05°53' Leo -1.9 32"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 56° from the Sun, which is in Libra at this time of year.
