It reached to 6 mag at best in early May at the remarkable approach to the earth, when it became double naked eye comets with the component B around the zenith. Now it is going away from the earth and fading. It has already faded down to 10.5 mag (July 7, Juan Jose Gonzalez). The apparent distance between the two components is reduced and two bright comets are now in the same field of a photo. It is getting higher again in the morning sky also in the Northern Hemisphere.

The condition is worst in this time, not visible in the Northern Hemisphere at all. It was observed in the Southern Hemisphere as 11.4 mag on June 6, as bright as expected (Michael Mattiazzo). However, in this appearance, the comet will never be observable again.

It brightened much more rapidly than expected after late April, and reached to 9.5 mag on June 15 (Willian Souza). Now it is 10.3 mag (Juny 28, Juan Jose Gonzalez). It is fading now, but it keeps observable in the evening until autumn when it becomes too faint to see. It keeps locating around 30 degree high. Great outburst over 6 mag has occured always in recent appearances in 1995 and 2001. So it may brighten much more after this.

It reached to 5 mag at best in early May at the remarkable approach to the earth, when it became double naked eye comets with the component C around the zenith. Now it is going away from the earth and fading. It had faded down to 8.5 mag on June 10 (Willian Souza). No observations were reported recently, but it will be fainter than 11 mag now. The apparent distance between the two components is reduced and two bright comets are now in the same field of a photo. It is getting higher again in the morning sky also in the Northern Hemisphere. Since mid May, no nuclear split or outburst has occured at all.

New comet discovered on the SWAN images. Now it is only observable in the Southern Hemisphere. Even in the Southern Hemisphere, it will be unobservable soon. In the Northern Hemisphere, it will appear at 7.5 mag in the extremely low sky at dawn in late September. It will turn to locate in the evening sky after early October. Then it keeps observable in the evening sky until early January while fading gradually. In the Southern Hemisphere, it cannot be observable until next April when it becomes fainter than 15 mag.

Now it is brightest and reached to 11.0 mag (June 15, Willian Souza). It keeps 11-12 mag until July. The condition is best beucase it is almost at opposition at the perihelion passage. However, it keeps very low, only about 15 degree high until September in the Northern Hemisphere. When it gets higher again, it will be fainter than 14 mag, too faint to see visually.

It was 15.0 mag on June 13 (Giovanni Sostero and Ernesto Guido), brightening as expected. It will become visible visually soon. It will be brightening rapidly after this, and will reach to 8.5 mag from autumn to winter, and observable in its best condition. It keeps 14 mag still in 2007 April, so it keeps visible visually for a long time.

Recovered after 117 year blank since 1889. It is already visible visually at 13.2 mag (July 7, Juan Jose Gonzalez). This time it will be closer to the earth than at the discovery. It moves northwards rapidly and keeps observable in good condition at 12-13 mag until September in the Northern Hemisphere. Based on the brightness in 1889, it can be much britghter than this ephemeris. However, because it is very close to the earth, it will look very diffuse.

It had been observed at 10 mag in the evening sky from winter to spring. But now it is not observable. It will appear in the morning sky again in late August at 13.5 mag. It will come to locate high in October, then it will be visible visually again at 14 mag.

New comet just discovered on June 14. It is bright as 13.4 mag and visible visually (June 16, Willian Souza). In the Northern Hemisphere, it locates rather low in the evening. In the Southern Hemisphere, it locates high. It will be observable at 13 mag for a long time after this.

It was observed as 12 mag in spring. It was diffuse visually, but bright and enjoyable with a large telescope. It was still bright as 12.8 mag on June 25 (Carlos Labordena).

It has been visible at 13.5 mag since last October. Small and strongly condensed. It kept observable in good condition for a long time, but it will be getting lower in the evening, and will be too low to observe soon.

Although it was not observed in its last return in 1999, it is observable in good condition after the periheliion passage in this return. Now it is brightest. But actually, it was 18.6 mag, much fainter than this ephemeris by 4-5 mag (June 30, Filip Fratev). In this appearance, it will never be brighter than 18 mag and it will fade out after this.

It has been lost since its discovery in 1986. The condition is good in this return. In calculation, it will be 14 mag from autumn to winter. However, it was probably in outburst and brightened unexpectedly at the discovery. So it can be much fainer than this ephemeris actually. In the Northern Hemisphere, it keeps observable until it fades out in next spring.

It was in major outburst unexpectedly and reached to 10.5 mag in its last appearance in 1999. It was already recovered in 2005 October. But it has not been observed for about 1 year since that. So the current brightness is quite uncertain. It will appear in the morning sky at 15.5 mag in September, then it will fade out gradually. But actually, it can be much fainter than this ephemeris.

It is outside of Jupiter's orbit, so it keeps observable for a long time. In 2006, it is still faint and locating somewhat low. But in 2007 and 2008, it is expected to be bright as 14.5-15 mag. It will locate high at that time, so it may be visible visually.

It was fantastic, so bright as 3.5 mag, so large as 30 arcmin, locating high overhead at its best time in early 2004 January. Then it has been getting fainter gradually, and become already too faint to see visually. However, it is still bright as 15.8 mag by CCD observations (Mar. 30, Katsumi Yoshimoto).
