Now it is so bright as 4.7 mag (June 12, Marco Goiato). The apparent size is so large as 20 arcmin. Now it is brightest, and it keeps 4.5 mag in June. Now it is not observable in the Northern Hemisphere, 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.

Great outburst occured on Oct. 24, and it bacame a naked eye comet of 2 mag. It kept so bright as 5.5 mag still on Apr. 30 (Carlos Labordena), but it was extremely faint and difficult to see. The size was so large, the diameter was larger than 60 arcmin. It is not observable in this summer. But it will become observable in good condition in autumn again. The extremely faint large diffuse object may be detected with a best sky condition, around 5-6 mag with a diameter of 1 or 2 degrees.

It is already very bright as 9.9 mag (June 6, Marco Goiato). Brightening well, and expected to be 6 mag in September. 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 6 mag in late September, but it keeps locating in the evening low sky until the end of 2008 when it fades out down to 9 mag. Then it turns to appear in the morning sky, and it keeps observable in the northern sky after that while fading gradually. In the Southern Hemisphere, it keeps observable until late October after this.

It will reach to 11 mag in summer. It must have already brightened up to 12 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.

It is already bright as 14.7 mag and visible visually (Mar. 5, Seiichi Yoshida). It is expected to reach to 11 mag in 2009 summer. Because it moves in the northern sky, it keeps observable until it becomes brightest in the Northern Hemisphere. But it becomes low from April to June.

Now it is 16.1 mag, brightening well as expected (Mar. 30, S. G. McAndrew). It is expected to brighten up to 10 mag from late 2009 to early 2010.

But after 2009 October, it is observable at 10 mag for a while in good condition. In the Southern Hemisphere, it keeps observable for a long time while brightening until 2009 June when it brightens to 11 mag. But it becomes unobservable around and after the brightest time.

It was observed at 16.5-17 mag in 2006 and 2007. Because it is a very distant comet, it is observable at 17 mag still in 2008 in good condition.

Although it was so faint as 20 mag still in January, it brightened rapidly and reached up to 17.1 mag now (May 15, Yasukazu Ikari). It is observable in good condition until summer.

No observations have been succeeded since 2007 July. It was predicted to be so bright as 14 mag now. But actually, it is fainter than 19 mag and not detectable (June 1, Gustavo Muler). It will locate in good condition from spring to summer. But it seems to have already disappeared.

The condition in the Northern Hemisphere was very good in first half of May, and it was observed at 16 mag. It will approach to the sun down to 0.1 A.U. on June 17. If it shows a cometary activity, it may become much brighter than this ephemeris. However, it is not observable on the earth.
