Across much of the world, the globular cluster NGC 6397 (mag 5.6) in Ara will be well placed in the evening sky in coming weeks. On 17 June 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 San Diego , however, it is not readily observable since it lies so far south that it will never rise more than 3° above the horizon.

At a declination of 53°40'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 16°N.

At magnitude 5.6, NGC6397 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 position of NGC6397 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
NGC6397 17h40m40s 53°40'S Ara 5.6 0'00"

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.
