Comet C/2014 Q2 (Lovejoy) puts on a show

Comet C/2014 Q2 (Lovejoy) was discovered (at magnitude +14.8) by T. Lovejoy (Birkdale, Qld., Australia) on 17 August 2014 on CCD images obtained with a 20-cm f/2.1 Schmidt-Cassegrain telescope. It is the fifth comet discovered by Terry Lovejoy.

On 7 January 2015, comet C/2014 Q2 passed 0.469 AU (1 AU = ~150 million kilometers) from Earth and it will reach the perihelion (closest approach to the Sun) on 30 January 2015 at a distance of 1.29 AU from the Sun. Comet Lovejoy reached few days ago its peak brightness at about magnitude +3.8, as bright as it should get, making it a naked-eye object. It is currently still at about magnitude +4.3. See below an updated light-curve.
