The globular cluster M2 (NGC 7089; mag 6.6) in Aquarius will be well placed in the evening sky in coming weeks. On 15 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 Cambridge , it is visible in the evening sky, becoming accessible around 20:57 (EST), 24° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:38, 46° above your southern horizon. It will continue to be observable until around 04:33, when it sinks below 21° above your south-western horizon.
At a declination of 0°49'S, it is visible across much of the world; it can be seen at latitudes between 69°N and 70°S.
At magnitude 6.6, M2 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 M2 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| M2 | 21h33m20s | 0°49'S | Aquarius | 6.6 | 0'00" |
The coordinates above are given in J2000.0.
