Across much of the world the brightest globular cluster in the sky, omega Centauri, will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -47°28′, it is easiest to see from the southern hemisphere and cannot be seen from latitudes much north of 22°N.

From London (click to change), it will not be observable because it will lie so far south that it never rises above the horizon.

At magnitude 3.7, ω-Cen is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.

The precise position of ω-Cen is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
ω-Cen 13h26m40s -47°28′ Centaurus 3.7 36’18”

The coordinates above are given in J2000.0.
