Now it is 10.7 mag (Oct. 4, Sandor Szabo). It is expected to be a great comet in 2013 autumn when the comet approaches to the sun down to only 0.01 A.U. It keeps visible with naked eyes from November to January, and can be extremely bright as Venus or more at the highlight. But recently, it is fainter than originally expected by 2 mag. It may be 3 mag at best actually when it is observable in the morning sky. The condition is excellent in the Northern Hemisphere. It keeps observable almost all through the period of brightening, at the highlight, and of fading. The condition is not good in the Southern Hemisphere. It is not observable at all the latter part of the highlight, and it keeps low all through the period.

It brightened up to 9.0 mag in 2012 autumn (Nov. 4, Juan Jose Gonzalez). However, it faded out unexpectedly around the perihelion passage. Now it is fainter than originally predicted by 4-5 mag. It has already faded down to 17.6 mag (Aug. 31, A. Maury, J. F Soulier, T. Noel, J. G. Bosch). In the Southern Hemisphere, it keeps observable in good condition while fading slowly after this. In the Northern Hemisphere, it will not be observable after this.

Although it was expected to be bright as 16 mag, actually it was so faint as 18.7 mag, fainter than expected by 2-3 mag (Sept. 15, P. C. Sherrod, L. P. Sherrod). It will be observable in good condition from summer to autumn, however, it will be only 18-19 mag at best.

It will approach to the Sun down to 0.9 A.U., and to the Earth down to 0.4 A.U. in September. So it was expected to brighten up to 11-12 mag. However, it looked extremely diffuse on July 12 by Michael Jager. So the comet could be already disintegrated at that time. No observations have been reported after that. It keeps locating in good condition after this in the Southern Hemisphere. It is not observable in the Northern Hemisphere.
