The globular cluster M12 (NGC 6218; mag 6.7) 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 1°56'S, it is visible across much of the world; it can be seen at latitudes between 68°N and 71°S.

From San Diego, it will be visible all night. It will become visible around 21:01 (PDT), 26° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:48, 55° above your southern horizon. It will be lost to dawn twilight around 04:29, 27° above your south-western horizon.
