(Barycentric solution for epoch 2050)
|Next perihelion||27 August 2014|
The comet starts 2014 as a northern hemisphere object. By late April 2014 it is expected to have brightened to roughly apparent magnitude ~9 making it a small telescope/binoculars target for experienced observers.
The comet will come to perihelion (closest approach to the Sun) on 27 August 2014 at a distance of 1.05 AU (157,000,000 km; 98,000,000 mi) from the Sun. It crosses the celestial equator on 15 September 2014 becoming a southern hemisphere object.
The comet should reach its peak magnitude of ~6 in mid-October 2014 when it will have an elongation of around 75 degrees from the Sun. It may be visible to the naked eye, but will be much easier to detect in binoculars.
