The open star cluster IC 4665 (mag 4.2) in Ophiuchus will be well placed in the evening sky in coming weeks. On 18 June it will reach its highest point in the sky at around midnight local time, and on subsequent evenings it will culminate four minutes earlier each day.

From Fairfield , it is visible all night. It will become visible at around 21:53 (EDT), 36° above your south-eastern horizon, as dusk fades to darkness.
