The open star cluster IC 4665 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 +05°43', it is visible across much of the world; it can be seen at latitudes between 75°N and 64°S.

From Ashburn (click to change), it will be visible all night. It will become visible at around 21:58 (EST) as the dusk sky fades, 36° above your south-eastern horizon. It will be lost to dawn twilight at around 04:23, 35° above your south-western horizon.

At magnitude 4.2, IC4665 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 IC4665 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
IC4665 17h46m10s +05°43' Ophiuchus 4.2 41'00"
