The globular cluster M15 (NGC 7078; mag 6.2) in Pegasus will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.
At a declination of +12°10', it is easiest to see from the northern hemisphere; it can be seen at latitudes between 82°N and 57°S.
From Fairfield, it will be visible all night. It will become visible around 21:10 (EDT) as the dusk sky fades, 33° above your eastern horizon. It will then reach its highest point in the sky at 00:58, 61° above your southern horizon. It will be lost to dawn twilight around 04:46, 32° above your western horizon.
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' | Pegasus | 6.3 | 12'18" |
The coordinates above are given in J2000.0.
