It will approach down to 0.4 A.U. to the sun on Oct. 28, and it is expected to reach to 6 mag. However, it was much fainter than expected recently, 17.5 mag on June 17 (Michael Jager) and 18.1 mag on July 25 (Luca Buzzi). The condition in the Northern Hemisphere is very hard. It locates extremely low, slightly over the horizon in the morning sky, from late September to mid October, then it will never be observable again. In the Southern Hemisphere, it will appear in the evening sky in early November, then it keeps observable while fading gradually, although it will not locate very high. It is expected to appear at 7 mag, but it can be much fainter actually.

Excellent great comet, few times in a lifetime, for southern people. It reached to -5.5 mag on Jan. 14 and 15, brighter than Venus, and visible even in daytime. Then it appeared in the evening sky in the Southern Hemisphere and many people enjoyed a fantastic view of a beautiful great comet, a enormous curving tail with so many striae over 50 degrees. It has already faded down to 12.6 mag (July 6, Walter Ruben Robledo). In the Southern Hemisphere, It keeps observable almost all night until the comet has gone. It will never be observable again in the Northern Hemisphere.
