Great outburst occured on Oct. 24, and it bacame a naked eye comet of 2 mag. It still keeps so bright as 5.5 mag on Apr. 30 (Carlos Labordena). Now it is extremely faint and difficult to see. It was completely stellar just after the outburst. Then the coma had spread out and now it looks like a huge nebula. The coma diameter has increased up to about 90 arcmin in December and January. But now it is going away from the earth, and the diameter reduced to about 60 arcmin. Now it is getting lower and lower rapidly in the evening sky. It will be unobservable soon. But it will become observable in good condition in autumn again.

It is brightening much faster than expected. It is already so bright as 6.2 mag (May 14, Marco Goiato). The apparent size is so large as 20 arcmin. It will pass 0.85 A.U. from the sun in late June, and it may reach up to 4.5 mag. In the Northern Hemipshere, it is observable until around May 25, when the comet will be 6 mag. It will be unobservable for one and a half month around the perihelion passage. But it will appear in the morning sky again at 5.5 mag in early July, then it keeps observable after that while the comet is fading gradually. In the Southern Hemipsphere, it keeps observable all the period until the comet fades out, although it will be low in mid June.

It passed near by Earth in early January, and it became a bright large object at 5.4 mag (Jan. 3, Seiichi Yoshida). It was visible with naked eyes. Now it is fading rapidly. It has already faded down to 11.3 mag (May 10, Marco Goiato). It will be fainter than 13 mag in late May. It has already moved away towards the southern sky, and it is no longer observable in the Northern Hemisphere. In the Southern Hemisphere, it keeps observable until it fades out.

It is already very bright as 10.7 mag (May 14, Marco Goiato). It is expected to be 7 mag in September, but it is getting brighter than expected. However, it keeps moving in the southern sky, and it is unobservable for a while in the Northern Hemisphere. It will appear in the evening sky at 7 mag in late September, but it keeps locating in the evening low sky until the end of 2008 when it fades out down to 10 mag. Then it turns to appear in the morning sky, and it keeps observable in the northern sky after that while fading gradually.

Now it is 13.0 mag (Apr. 27, J. Broughton), brightening as expected. It will reach to 10.5 mag and will be observable in good condition in 2008 autumn.

It will reach to 11 mag in summer. It must have already brightened up to 14 mag, but the comet was not observed recently. The condition in this apparition is bad. In the Southern Hemisphere, it keeps extremely low, or under the horizon, so it will not be observable. In the Northern Hemisphere, it is not observable until August when it appears in the morning sky at 11 mag. After August, it keeps observable and fading in the morning sky.

New comet. It is bright as 12.7 mag, and visible visually (May 12, Juan Jose Gonzalez). It keeps observable in good condition until autumn. But it is moving southwards gradually, and the altitude will be getting somewhat lower in the Northern Hemisphere. The calculation says it keeps bright at 13 mag for a while. However, it can be in a temporary outburst now, and it may be a very faint short periodic comet originally. It may fade out very rapidly after this.

After an outburst on Dec. 29, some outbursts occured repeatedly until mid January. It became very bright as 10.4 mag on Jan. 15 (P. Clay Sherrod). Then it is fading gradually.

Although it had been extremely fainter than expected until March, it brightened very rapidly in April. It became very bright and visible visually at 11.3 mag (Apr. 12, Marco Goiato). However, it was difficult to see because extremely diffuse. CCD observers reported it so faint as 15 mag. This comet tends to be brightest after the perihelion passage. In the Northern Hemisphere, it had been low until March, but now it locates high. It will be visible visually at 12-13 mag until early May in the good condition.

It was observed bright at 16.5-17 mag from late 2006 to early 2007. However, it is fading after that, although it is getting closer to the sun. Now it is observable in good condition, but very faint at 19.4 mag (Mar. 10, Mitsunori Tsumura). This comet was observed so faint around the perihelion passage in the previous apparition at the discovery. It faded out before the perihelion passage again in this apparition.
