The globular cluster M15 (NGC 7078; mag 6.3) in Pegasus will be well placed in the evening sky in coming weeks. On 13 August 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 South El Monte , it is visible all night. It will become visible at around 20:44 (PDT), 30° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:53, 68° above your southern horizon. It will be lost to dawn twilight at around 05:06, 28° above your western horizon.
At a declination of 12°10'N, it is easiest to see from the northern hemisphere; it can be seen at latitudes between 82°N and 57°S.
At magnitude 6.3, M15 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 M15 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| M15 | 21h29m50s | 12°10'N | Pegasus | 6.3 | 11'06" |
The coordinates above are given in J2000.0.
