The open star cluster NGC 6633 (mag 4.6) in Ophiuchus will be well placed in the evening sky in coming weeks. On 28 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 San Diego , it is visible all night. It will become visible around 21:10 (PST), 34° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:45, 63° above your southern horizon. It will be lost to dawn twilight around 04:31, 31° above your western horizon.

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.
