Comet Lovejoy - 2014 Dec 28
Comet Lovejoy (C/2014 Q2) is a long-period comet discovered on 2014 August 17 by Terry Lovejoy using a 0.2-meter (8-in) Schmidt–Cassegrain telescope. It was then shining at apparent magnitude 15 in the southern constellation Puppis. This the fifth comet discovered by Terry Lovejoy. One of his previous comets (C/2013 R1) was widely viewed in 2013.
Since its discovery, Comet Lovejoy has been approaching the Sun and climbing northwards from the Southern Hemisphere. By mid-December the comet was far enough north to be viewed from the USA and Europe. Around the same time, Comet Lovejoy became visible to the naked eye for experienced observers from dark sky locations.
Throughout late December (2014) and January (2015), Comet Lovejoy with move further north as is expected to peak at about magnitude 4. The comet passes closest to Earth on 2015 Jan 07 at a distance of 0.469 AU (70,200,000 km or 43,600,000 mi).Perihelion (closest point to the Sun) occurs on 2015 Jan 30 at a solar distance of 1.291 AU (193,096,000 km or 119,985,000 mi).
