The globular cluster M12 (NGC 6218; mag 6.7) in Ophiuchus will be well placed in the evening sky in coming weeks. On 3 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 around 21:44 (EDT), 29° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:51, 46° above your southern horizon. It will be lost to dawn twilight around 03:56, 29° above your south-western horizon.

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.

At magnitude 6.1, M12 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

The position of M12 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
