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 but cannot be seen from latitudes much north of 46°N.
From Ashburn, it will be visible between 22:57 and 03:15. It will become accessible at around 22:57, when it rises 20° above your south-eastern horizon, and then reach its highest point in the sky at 01:08, 27° above your southern horizon. It will become inaccessible at around 03:15 when it sinks to 20° above your south-western horizon.
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:

The circumstances of this event were computed using the DE405 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.
