Across much of the world the globular cluster M22 in Sagittarius, near the Galactic centre, will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -23°54', it is easiest to see from the southern hemisphere and cannot be seen from latitudes much north of 46°N.

From London (click to change), it will not be readily observable since it will lie so far south that it will never rise more than 14° above the horizon.

At magnitude 5.1, M22 is too faint to be seen with the naked eye from any but the very darkest sites, but is visible through a pair of binoculars or small telescope.

The precise position of M22 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M22 18h36m20s -23°54' Sagittarius 5.1 0'24"

The coordinates above are given in J2000.0.
