It brightened up to 15.9 mag in June as predicted (June 23, Ken-ichi Kadota). It was expected to be observable at 13 mag in good condition from summer to autumn. However, Jean-Gabriel Bosch detected the comet became disintegrating in July. Now it is so faint as 19.3 mag (Aug. 26, W. Hasubick). The fragment D and B are also observed as 19.0 mag (Sept. 20, Michael Jager) and 20.9 mag (Aug. 21, Pan-STARRS 1, Haleakala) respectively.
