引用上面
The comet will increase its brightness; in August of 2011 it will be mag. 6-8.

By the end of the month and throughout September the comet will be hidden from earthly observers in the rays of the Sun, but it will be easily visible in images from the cosmic coronagraph. At that time the comet’s brightness will be at maximum – about mag. 3-4 (although with passage so close to the Sun anything can be expected). By the way, at that time the comet will again be at the same equatorial coordinates where it was discovered in December of 2010.
