It brightened more rapidly than expected, and reached to 7.2 mag on July 14 (Maik Meyer). It will be fading gradually after this. Now it is 8.1 mag (Aug. 3, Juan Jose Gonzalez). It kept observable in good condition for a while in the Northern Hemisphere. However, it moves southwards very fast in August. It is only observable until mid August in the Northern Hemisphere. On the other hand, it became observable since mid July in the Southern Hemisphere.

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.

In the Southern Hemisphere, now it is low temporarily. But it will be high after this, then it keeps observable in good condition until 2008 summer. In the Northern Hemisphere, it will appear at 13 mag in November in a short time, but very low and hard to observe.

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.
