The Moon and Neptune will make a close approach, passing within a mere 9.6 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 25 days old.

From South El Monte , the pair will be visible in the dawn sky, rising at 01:30 (PDT) and reaching an altitude of 43° above the south-eastern horizon before fading from view as dawn breaks at around 05:09.

The Moon will be at mag -11.3; and Neptune will be at mag 8.0. 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:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 59° from the Sun, which is in Libra at this time of year.
