M19 Observation Details
M19 Daily Motion
M19 will rise at 14:33, reaching 62° when twilight begins at 19:54. It will reach transit at 64° by 20:32 and will set before twilight ends at 02:31.M19 will be visible until October, 25, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.

M19 - Globular Cluster
M19 is a globular cluster located in the constellation Ophiuchus. It was discovered by Charles Messier in 1764. This cluster is one of the most oblate (flattened) globular clusters known.
M19 spans about 140 light-years across and contains tens of thousands of stars. The cluster is approximately 28,700 light-years away from Earth and has an apparent magnitude of 6.8, making it visible with binoculars or a small telescope.
