Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

C/2014 Q2 (Lovejoy) _15-1-2015

C/2014 Q2 (Lovejoy) is a long-period comet discovered on 17 August 2014 by Terry Lovejoy using a 0.2-meter (8 in) Schmidt–Cassegrain telescope.[1] It was discovered at apparent magnitude 15 in the southernconstellation of Puppis.[1] It is the fifth comet discovered by Terry Lovejoy.

By December 2014, the comet had brightened to roughly magnitude 7.4,[4] making it a small telescope and binoculars target. By mid-December, the comet was visible to the naked eye for experienced observers with dark skies and keen eyesight.[5] On 28−29 December 2014, the comet passed 1/3° from globular cluster Messier 79.[6] In January 2015, it brightened to roughly magnitude 4−5,[7] and became one of the brightest comets located high in a dark sky in years. On 7 January 2015, the comet passed 0.469 AU (70,200,000 km; 43,600,000 mi) from Earth.[8] It crossed the celestial equator on 9 January 2015 becoming better seen from thenorthern hemisphere.[9] The comet will come to perihelion (closest approach to the Sun) on 30 January 2015 at a distance of 1.29 AU (193,000,000 km; 120,000,000 mi) from the Sun.[2]

Before entering the planetary region (epoch 1950), C/2014 Q2 had an orbital period of about 11000 years.[3] After leaving the planetary region (epoch 2050), it will have an orbital period of about 8000 years.[3]
