The globular cluster M10 (NGC 6254; mag 6.6) 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 -04°05', it is visible across much of the world; it can be seen at latitudes between 65°N and 74°S.

From Fairfield, it will be visible all night. It will become visible around 21:46 (EDT) as the dusk sky fades, 28° above your south-eastern horizon. It will then reach its highest point in the sky at 00:56, 44° above your southern horizon. It will be lost to dawn twilight around 03:59, 28° above your south-western horizon.
