NGC 6530 is well placed

Across much of the world the open star cluster NGC 6530, close to the lagoon nebula (M8) 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 -24°19', it is easiest to see from the southern hemisphere and cannot be seen from latitudes much north of 45°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 14° above the horizon.

At magnitude 4.6, NGC6530 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 NGC6530 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
NGC6530 18h04m40s -24°19' Sagittarius 4.6 0'15"

The coordinates above are given in J2000.0.
