The Great Globular Cluster in Hercules (M13, NGC 6205; mag 5.8) will be well placed in the evening sky in coming weeks. On 2 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 Columbus , it is visible all night. It will become visible at around 22:15 (EST), 53° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 01:28, 86° above your southern horizon. It will be lost to dawn twilight at around 04:42, 52° above your western horizon.
At a declination of 36°27'N, it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 33°S.
At magnitude 5.8, M13 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 M13 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| M13 | 16h41m40s | 36°27'N | Hercules | 5.8 | 0'00" |
The coordinates above are given in J2000.0.
