Across much of the world the globular cluster M55 (NGC 6809) in Sagittarius will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -30°57', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 39°N.

From Cambridge, it will not be readily observable since it will lie so far south that it will never rise more than 16° above the horizon.

At magnitude 6.3, M55 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 M55 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M55 19h39m50s -30°57' Sagittarius 6.3 19'00"
