Comet C/2011 W3 Lovejoy

Updated 1 January 2012

The comet was discovered by Australian amateur astronomy Terry Lovejoy on 27 November 2011. The comet grazed past the Sun on 16 December and was not expected to survive. However it did, and put on a magnificent display during Christmas 2011. This is Terry Lovejoy's third comet, which he discovered using an 8-inch Schmidt-Cassegrain telescope with a QHY9 CCD camera.


Where and when to look

The comet is situated in the south-eastern sky near the Milky Way. It is visible all night long, but is best observed in the morning (before twilight) as it is higher above the horizon.

The comet has now faded significantly and is too faint to be observed from light-polluted metropolitan areas. To see the comet, you will need to travel to the country where the skies are much darker. It is important that you ensure that your south-easterly horizon does not overlook populated areas otherwise your view will be compromised by the effect of light pollution. Avoid light! You should attempt to adapt your eyes to the darkness.

Astronomical twilight ends at 4:15am.

How to observe

We recommend at least a pair of binoculars to observe the comet -- 7 x 50 mm are ideal. As the comet has now faded, the best way to see the comet is by taking a long exposure (30 seconds or more) using a digital camera.
