The globular cluster M22 (mag 5.2) in Sagittarius, near the Galactic centre, will be well placed in the evening sky in coming weeks. On 1 July it will reach its highest point in the sky at around midnight local time, and on subsequent evenings it will culminate four minutes earlier each day.
From Cambridge , it is visible between 23:07 and 02:11. It will become accessible at around 23:07, when it rises to an altitude of 20° above your south-eastern horizon. It will reach its highest point in the sky at 00:39, 23° above your southern horizon. It will become inaccessible at around 02:11 when it sinks below 20° above your southern horizon.
At a declination of 23°54'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 46°N.
At magnitude 5.2, 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 position of M22 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| M22 | 18h36m20s | 23°54'S | Sagittarius | 5.2 | 0'00" |
The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
