Across much of the world, the second brightest globular cluster in the sky , 47 Tuc (NGC 104; mag 4.0), in Tucana will be well placed in the evening sky in coming weeks. On 27 September 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 Cambridge , however, it is not observable because it lies so far south that it never rises above the horizon.
At a declination of 72°04'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 2°S.
At magnitude 4.0, NGC104 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 position of NGC104 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| NGC104 | 00h24m00s | 72°04'S | Tucana | 4.0 | 0'00" |
The coordinates above are given in J2000.0.
