M4 is well placed

2019 May 28

Across much of the world the globular cluster M4 (NGC 6121) in Scorpius will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -26°31', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 43°N.

From London, it will not be readily observable since it will lie so far south that it will never rise more than 11° above the horizon.

At magnitude 5.9, M4 is quite faint, and certainly not visible to the naked eye, but can be viewed 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' Scorpius 5.9 26'18"

The coordinates above are given in J2000.0.
