The open star cluster NGC 6633 in Ophiuchus will be well placed for observation. It will reach its highest point in the sky at around midnight local time.
At a declination of +06°30', it is visible across much of the world; it can be seen at latitudes between 76°N and 63°S.
From Cambridge, it will be visible all night. It will become visible at around 21:49 (EST) as the dusk sky fades, 37° above your south-eastern horizon. It will be lost to dawn twilight at around 03:38, 37° above your south-western horizon.
At magnitude 4.6, NGC6633 is too faint to be seen with the naked eye from any but the very darkest sites, but is visible through a pair of binoculars or small telescope.
The position of NGC6633 is as follows:
