The open star cluster NGC 869 in Perseus, also known as the western half of the double cluster will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +57°07', it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 12°S.

From Ashburn (click to change), it will be visible all night. It will become visible at around 19:21 (EDT) as the dusk sky fades, 33° above your north-eastern horizon. It will be lost to dawn twilight at around 06:27, 37° above your north-western horizon.

At magnitude 3.7, NGC869 is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.

The position of NGC869 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
NGC869 02h18m50s +57°07' Perseus 3.7 30'00"

The coordinates above are given in J2000.0.
