Across much of the world, the brightest globular cluster in the sky , Omega Centauri (mag 3.6) will be well placed in the evening sky in coming weeks. On 13 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 Jacksonville , however, it is not readily observable since it lies so far south that it will never rise more than 12° above the horizon.
At a declination of 47°28'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 22°N.
At magnitude 3.6, NGC5139 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 NGC5139 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| NGC5139 | 13h26m40s | 47°28'S | Centaurus | 3.6 | 27'00" |
The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE430 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.
