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 and cannot be seen from latitudes much north of 43°N.
From London (click to change), 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 5.6, 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 precise position of M4 is as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0.
