New comet. It will approach to the sun down to 0.3 a.u. in 2015 July, and it is expected to be bright. Now it is 16.7 mag (Aug. 22, iTelescope Observatory, Siding Spring). It keeps observable while the comet will be brightening gradually until January when the comet will be 15 mag. The condition is bad after that and it will be hard to observe. But in the Southern Hemisphere, it will be observable after mid July in 2015, and keeps observable while the comet will be fading gradually. In the Northern Hemisphere, it is extremely hard to observe after 2015.

First return of a new periodic comet discovered in 2005. It was expected to be observable at 17 mag for a long time from 2013 to 2014. However, it has not been recovered yet. Actually, it is much fainter than predicted, fainter than 20.5 mag (Aug. 1, Jean-Francois Soulier).

It will brighten up to 14 mag around the perihelion passage in 2019. In 2014, it will be observable in excellent condition at 17 mag from summer to winter in the Northern Hemisphere. It locates extremely low in the Southern Hemisphere. However, it is so faint as 20.2 mag now, much fainter than this ephemeris by 3 mag (July 27, J. Vinko, R. Szakats, K. Sarneczky).

It was observed at 17.5 mag in early 2013. It was predicted to be observable at 17.5 mag again from spring to summer in 2014. But actually, it is 20.6 mag (June 21, Hidetaka Sato), much fainter than predicted by 3 mag.

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.
