Now it is so bright as 9.8 mag (Sept. 13, Juan Jose Gonzalez). Getting lower graudally in the evening sky. It will be unobservable in late September in the Southern Hemisphere, or in mid October in the Northern Hemisphere. In the Southern Hemisphere, it will appear in the morning sky at 9 mag in 2013 February, then it keeps observable in good condition while fading slowly. In the Northern Hemisphere, it is hardly observable after 2013.
