Across much of the world, the Jewel Box open star cluster (NGC 4755, also known as the Kappa Crucis Cluster; mag 4.2) in Crux will be well placed in the evening sky in coming weeks. On 5 April it will reach its highest point in the sky at around midnight local time, and on subsequent evenings it will culminate four minutes earlier each day.

From Ashburn , however, it is not observable because it lies so far south that it never rises above the horizon.

At a declination of 60°21'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 9°N.

At magnitude 4.2, NGC4755 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 position of NGC4755 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
NGC4755 12h53m30s 60°21'S Crux 4.2 0'00"
