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.
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|
