The open star cluster NGC 6633 (mag 4.6) in Ophiuchus will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.

At a declination of 6°30'N, it is visible across much of the world; it can be seen at latitudes between 76°N and 63°S.

From Fairfield, it will be visible all night. It will become visible around 21:56 (EDT), 38° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:52, 55° above your southern horizon. It will be lost to dawn twilight around 03:56, 36° above your south-western horizon.
