The Moon and 1 Ceres will make a close approach, passing within a mere 24.3 arcminutes of each other. The Moon will be 15 days old.

From South El Monte , the pair will be visible in the morning sky, becoming accessible around 23:57, when they reach an altitude of 21° above your south-eastern horizon. They will then reach their highest point in the sky at 02:26, 31° above your southern horizon. They will be lost to dawn twilight around 04:31, 24° above your south-western horizon.

The Moon will be at mag -12.5; and 1 Ceres will be at mag 7.5. Both objects will lie in the constellation Sagittarius.

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 1 Ceres 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 18h01m30s 24°29'S Sagittarius -12.5 30'26"5
1 Ceres 18h01m20s 24°05'S Sagittarius 7.5 0"0

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