The Moon and Neptune will make a close approach, passing within a mere 2.0 arcminutes of each other. From some parts of the world, the Moon will pass in front of Neptune, creating a lunar occultation. The Moon will be 17 days old.

From Columbus , the pair will be visible in the morning sky, becoming accessible around 21:22, when they reach an altitude of 21° above your eastern horizon. They will then reach their highest point in the sky at 02:09, 62° above your southern horizon. They will be lost to dawn twilight around 06:32, 26° above your western horizon.

The Moon will be at mag -12.7; and Neptune will be at mag 7.9. Both objects will lie in the constellation Leo.

They will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

A graph of the angular separation between the Moon and Neptune around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 10h00m10s 12°45'N Leo -12.7 31'21"9
Neptune 10h00m00s 12°43'N Leo 7.9 2"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 157° from the Sun, which is in Capricornus at this time of year.
