The globular cluster M3 (NGC 5272; mag 6.2) in Canes Venatici 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 28°22'N, it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 41°S.
From Cambridge, it will be visible all night. It will become visible around 20:41 (EDT), 39° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:45, 75° above your southern horizon. It will be lost to dawn twilight around 04:49, 39° above your western horizon.
At magnitude 6.3, M3 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 M3 is as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
