Across much of the world the butterfly open star cluster (M6, NGC 6405) 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 -32°13', it is easiest to see from the southern hemisphere and cannot be seen from latitudes much north of 37°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 6° above the horizon.

At magnitude 4.2, M6 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 M6 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M6 17h40m00s -32°13' Scorpius 4.2 0'15"

The coordinates above are given in J2000.0.
