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°34', it is visible across much of the world; it can be seen at latitudes between 76°N and 63°S.

From Ashburn (click to change), it will be visible all night. It will become visible at around 21:59 (EST) as the dusk sky fades, 36° above your south-eastern horizon. It will be lost to dawn twilight at around 04:27, 35° 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:

Object Right Ascension Declination Constellation Magnitude Angular Size
NGC6633 18h27m40s +06°34' Ophiuchus 4.6 27'00"

The coordinates above are given in J2000.0.
