Now it is visible in the image of SOHO spacecraft. It is very bright as 2.1 mag (June 26, Mieczyslaw Leszek Paradowski). It approaches to Sun down to 0.3 a.u. on July 3, and brightens up to 0-1 mag. Now it is not observable on the ground. It will appear in the evening sky at 3-4 mag in mid July in the Northern Hemisphere, or at 5 mag in late July in the Southern Hemisphere. Then it stays observable while getting fainter.
