Across much of the world the jewel box open star cluster (NGC 4755, also known as the kappa Crucis cluster) in Crux will be well placed for observation. It will reach its highest point in the sky at around midnight local time.
At a declination of -60°19', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 9°N.
From Ashburn (click to change), it will not be observable because it will lie so far south that it never rises above the horizon.
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|
The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
