The Moon and Mars will make a close approach, passing within a mere 15.7 arcminutes of each other. From some parts of the world, the Moon will pass in front of Mars, creating a lunar occultation. The Moon will be 20 days old.
From South El Monte , the pair will be visible in the morning sky, becoming accessible around 00:49, when they reach an altitude of 9° above your south-eastern horizon. They will then reach their highest point in the sky at 04:58, 35° above your southern horizon. They will be lost to dawn twilight around 06:20, 31° above your southern horizon.
The Moon will be at mag -12.3 in Ophiuchus; and Mars will be at mag -0.3 in Scorpius.
They will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.
At around the same time, the pair will also share the same right ascension – called a conjunction.
A graph of the angular separation between the Moon and Mars 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 | 16h23m20s | 20°23'S | Ophiuchus | -12.3 | 30'17"4 |
| Mars | 16h23m00s | 20°38'S | Scorpius | -0.3 | 10"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 117° from the Sun, which is in Pisces at this time of year.
