Now it is so bright as 9.3 mag (Oct. 5, Juan Jose Gonzalez). It will be unobservable soon. In the Southern Hemisphere, it will appear in the morning sky at 9 mag in 2013 February, then it keeps observable in good condition while fading slowly. In the Northern Hemisphere, it is hardly observable after 2013.

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. Now it is 17.2 mag (Oct. 12, A. Knoefel). 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.

The condition of this apparition is bad, and it was not observable around the perihelion passage. Now it is 16.5 mag (Oct. 6, Catalina Sky Survey). It will be fainter than 18 mag soon.

First return of a new periodic comet discovered in 1997 at 17 mag. Now it is 19.2 mag (Sept. 25, Mt. Lemmon Survey). It was expected to keep 17 mag for a long time from 2012 to 2014. But actually, it is fainter than predicted by 2 mag.

It was observed at 17 mag in 2011 autumn. It was expected to be observable at 17 mag in good condition again from autumn to winter in 2012. But actually, the comet is 19.4 mag (Sept. 29, G. Hug), much fainter than this ephemeris. Hidetaka Sato reported that it was not detected, fainter than 21.0 mag (Sept. 21). The comet must have faded out very rapidly.
