The globular cluster M4 (NGC 6121; mag 5.4) in Scorpius will be well placed in the evening sky in coming weeks. On 28 May 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 00:11 and 01:06. It will become accessible at around 00:11, when it rises to an altitude of 20° above your southern horizon. It will reach its highest point in the sky at 00:39, 21° above your southern horizon. It will become inaccessible at around 01:06 when it sinks below 20° above your southern horizon.

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.

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:

Object Right Ascension Declination Constellation Magnitude Angular Size
M4 16h23m30s 26°31'S Scorpius 5.4 28'12"

The coordinates above are given in J2000.0.
