Across much of the world, the globular cluster M55 (NGC 6809l; mag 6.3) in Sagittarius will be well placed in the evening sky in coming weeks. On 17 July 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 Washington , however, it is not readily observable since it lies so far south that it will never rise more than 21° above the horizon.

At a declination of 30°57'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 39°N.

At magnitude 6.3, M55 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

The position of M55 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M55 19h39m50s 30°57'S Sagittarius 6.3 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.
