The Rosette Nebula (C49; mag 9.0) in Monoceros will be well placed in the evening sky in coming weeks. On 29 December 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 , it is visible between 19:04 and 04:19. It will become accessible at around 19:04, when it rises to an altitude of 18° above your eastern horizon. It will reach its highest point in the sky at 23:42, 52° above your southern horizon. It will become inaccessible at around 04:19 when it sinks below 18° above your western horizon.
At a declination of 5°03'N, it is visible across much of the world; it can be seen at latitudes between 75°N and 64°S.
At magnitude 4.3, Caldwell 49 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 Caldwell 49 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Caldwell 49 | 06h32m10s | 5°03'N | Monoceros | 4.3 | 0'00" |
The coordinates above are given in J2000.0.
