In the Southern Hemisphere, it keeps observable until winter when the comet will be 13 mag. But it is not observable around the brightest days. In the Northern Hemispehre, it keeps extremely low and hard to observe. It will be observable after 2015 autumn when the comet will fade out.

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.
