It was expected to be bright as 17-18 mag. But actually, it is so faint as 20.3 mag (Oct. 11, Giovanni Sostero and Ermesto Guido). However, it was observed as bright as 17 mag in 1998 and 2005. So it will brighten after the perihelion passage, and will be bright up to 17 mag in 2011-2012 season also in this apparition. In the Northern Hemisphere, it will be observable in good condition while fading gradually after 2011 summer. It is not observable after the perihelion passage in the Southern Hemisphere.
