Mars and M22 will make a close approach, passing within a mere 45.8 arcminutes of each other.
From South El Monte , the pair will become visible at around 17:56 (PDT), 21° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 22 minutes after the Sun at 20:17.
Mars will be at mag 0.9; and M22 will be at mag 5.2. Both objects will lie in the constellation Sagittarius.
They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between Mars and M22 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 |
| Mars | 18h36m30s | 24°39'S | Sagittarius | 0.9 | 5"4 |
| M22 | 18h36m20s | 23°54'S | Sagittarius | 5.2 | 12'36"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 54° from the Sun, which is in Libra at this time of year.
