The globular cluster M4 (NGC 6121; mag 5.6) in Scorpius will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.
At a declination of 26°31'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 43°N.
From Cambridge, it will be visible between 00:17 and 01:13. It will become accessible around 00:17, when it rises to an altitude of 20° above your southern horizon. It will reach its highest point in the sky at 00:45, 21° above your southern horizon. It will become inaccessible around 01:13 when it sinks below 20° above your southern horizon.
At magnitude 5.4, M4 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 M4 is as follows:
