* C/2013 V5 ( Oukaimeden )

The brightness evolution has slowed down just before the perihelion passage. But now it is bright as 7.1 mag (Sept. 7, Marco Goiato). In the Southern Hemisphere, it is observable in the morning sky until mid September. Then it is observable in the evening sky from late September to mid October. In the Northern Hemisphere, it will be unobservable soon.

It was discovered in 1819, and re-discovered in 2003. Although it was predicted to be extremely faint as 26 mag, it unusually brightened up to 17.5 mag in outburst in 2013 July (July 6, Hidetaka Sato). However, no observations have been reported since mid July. It will pass the perihelion in 2014 August, and will approach to the sun down to 0.96 a.u. The brightness is predicted to be 23 mag at best. However, if the cometary activity continues, it may be observed brighter. Ken-ichi Kadota reported it was not detected, fainter than 16.3 mag, on May 21.
