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 Ashburn , it is visible all night. It will become visible at around 21:49 (EST), 52° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 01:04, 87° above your southern horizon. It will be lost to dawn twilight at around 04:24, 50° 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:

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.
