C/2013 V5 (Oukaimeden) is a retrograde Oort cloud comet discovered on 12 November 2013 by Oukaimeden Observatory at an apparent magnitude of 19.4 using a 0.5-meter (20 in) reflecting telescope.[1]

From 5 May 2014 until 18 July 2014 it had an elongation less than 30 degrees from the Sun.[4] By late August 2014 it had brighten to apparent magnitude 8[5] making it a small telescope and high-end binoculars target for experienced observers. It crossed the celestial equator on 30 August 2014 becoming a southern hemisphere object.[4] On 16 September 2014 the comet passed 0.480 AU (71,800,000 km; 44,600,000 mi) from Earth.[6] The comet peaked around magnitude 6.2 in mid-September 2014[7][8] but only had an elongation of about 35 degrees from the Sun.[4] On 20 September 2014 the comet was visible in STEREO HI-1B.[9] The comet came to perihelion (closest approach to the Sun) on 28 September 2014 at a distance of 0.625 AU (93,500,000 km; 58,100,000 mi) from the Sun.[2]

C/2013 V5 is dynamically new. It came from the Oort cloud with a loosely bound chaotic orbit that was easily perturbed by galactic tides and passing stars. Before entering the planetary region (epoch 1950), C/2013 V5 had an orbital period of several million years.[3] After leaving the planetary region (epoch 2050), it will have an orbital period of about 6000 years.[3]
