Across much of the world the second brightest globular cluster in the sky, 47 Tuc (NGC 104), in Tucana, will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -72°04', it is easiest to see from the southern hemisphere and cannot be seen from latitudes much north of 2°S.

From London (click to change), it will not be observable because it will lie so far south that it never rises above the horizon.

At magnitude 4.0, 47-Tuc is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.

The precise position of 47-Tuc is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
47-Tuc 00h24m00s -72°04' Tucana 4.0 30'54"

The coordinates above are given in J2000.0.
