Across much of the world, the Southern Pinwheel Galaxy M83 (NGC 5236; mag 7.2), a face-on spiral galaxy in Hydra will be well placed in the evening sky in coming weeks. On 16 April 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 readily observable since it lies so far south that it will never rise more than 17° above the horizon.
At a declination of 29°52'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 40°N.
At magnitude 7.2, M83 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 M83 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| M83 | 13h37m00s | 29°52'S | Hydra | 7.2 | 0'00" |
The coordinates above are given in J2000.0.
