It passed very near by the earth, within 0.1 A.U., and brightened up to 8.0 mag in the southern sky (Aug. 14, Willian Souza). It appeared in the morning sky in the Northern Hemisphere. Now it is very bright as 6.6 mag (Sept. 27, Jakub Koukal). It keeps observable while fading gradually after this. In the Southern Hemisphere, it is not observable until winter when it becomes fainter than 16 mag.

It has brightened faster than expected, and reached up to 8.1 mag in mid August (Aug. 19, Michael Mattiazzo). However, it turned to be fading and got diffuse rapidly after that. It has been already became fainter than 10.5 mag and unable to be detected (Sept. 14, Michael Mattiazzo). Altnough it was expected to be a naked eye comet, the nucleus is disintegrating and the comet will disappear soon. However, it was detected by STEREO spacecraft images at 12-13 mag still on Sept. 11 (Alan Watson). It will appear in the morning sky soon, tnen it becomes observable in the excellent condition at midnight. However, the comet can be already too faint to see.
