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. Yasukazu Ikari reported it was not detected, fainter than 15.5 mag, on May 23.
