It passes the perihelion on Apr. 19. Now it is so bright as 7.4 mag (Apr. 12, Vitali Nevski), although it locates extremely low in the evening sky. It will be unobservable in mid April. After conjunction with the sun, it appears in the morning sky at 12 mag in June. But it locates only 20 degree high at most, and it will be fading rapidly. In the Southern Hemisphere, it appears in the morning sky at 8 mag in May, then it will be bright and observable for a while.

The condition was too bad to observe on the earth before the perihelion passage, but it was visible in the SWAN images in mid March, and in the LASCO images in early April. After the perihelion passage on Apr. 4, it appeared in the morning sky. It was so bright as 5.5 mag on Apr. 10 (Michael Jager and Gerald Rhemann), and still bright as 7.8 mag on Apr. 15 (Edwin van Dijk). The condition will get better rapidly after this. However, the comet will fade out rapidly. It will be fainter than 14 mag in mid May, too faint to see visually.

New bright comet discovered visually in the Southern Hemisphere. It is moving northwards fast, and it appeared in the morning sky also in the Northern Hemisphere in early April. It is getting closer to the earth, and brightening up to 7.7 mag now (Apr. 15, Edwin van Dijk). It will be observable in good condition at 7-8 mag until mid May. Then it keeps observable until it fades out in the Northern Hemisphere. It will be visible visually until July.

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. Now it is observable both in the evening and morning. It has already faded down to 9.0 mag (Apr. 11, Jim Gifford). 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. It passes near by the Small Magellanic Cloud in early April.

Although it was so faint as 13.8 mag in March (Mar. 17, Alan Hale), it brightened very rapidly in early April, and it reached to 8.7 mag on Apr. 10 (Werner hasubick). Now it is observable in excellent condition. However, the comet is very large, extremely diffuse. It is hard to observe without clear skies. In addition, it will be fading after this, will be low in the evening sky soon, and will be unobservable in late May.

First return of a new bright periodic comet observed at 9 mag in 2001. It brightened rapidly also in this return. It was 16.1 mag on Jan. 11 (Filip Fratev), but it brightened up to 11.1 mag on Mar. 11 (Reinder J. Bouma). Unexpectedly, it became as bright as at the discovery, and visible visually. However, the condition of this apparition is bad. It keeps locating very low in the evening until early May. It has already turned to be fading.

Now it is 12.6 mag (Mar. 9, Edwin van Dijk). It has been 12 mag for half a year since last June. But it will start fading after this. It will be too faint to see visually soon. However, the fading is slow. The comet will be fainter than 18 mag in 2008. In the Northern Hemisphere, it keeps observable until that time. In the Northern Hemisphere, it keeps observable all night for a while after this.

It became brighter than expected, and now it is visible visually at 13.4 mag (Apr. 12, Vitali Nevski). It keeps observable in the evening sky until May. It is not observable around the perihelion passage in July in conjunction with the sun. Then it moves to the southern sky, and it will be unobservable in the Northern Hemisphere.

Now it is 14.4 mag (Feb. 12, Juan Jose Gonzalez). Almost asteroidal. It did not brighten at all since early September. Although the slight cometary activity was detected in late July, it became completely stellar soon. Its tail became visible again in late October, however, it turned to be stellar again soon. Finally it has passed the perihelion, keeping almost asteroidal. It kept observable at 14 mag in good condition in the Northern Hemisphere for a long time. However, it will be fading after this. It will start getting lower in April, and will be too low in the evening sky at 17 mag in June.

Now it is 18 mag. It will approach down to 0.4 A.U. to the sun in late October, and it is expected to reach to 6 mag. However, the condition in the Northern Hemisphere is very hard. It will be getting lower in the evening sky after this. The altitude becomes lower than 20 degree in early July, and lower than 10 degree in late July. The comet is still faint as 15.5 mag at that time. After conjunction with the sun, the comet will be brighter than 11 mag in late September, and will be 8 mag in mid October. But it locates extremely low, slightly over the horizon in the morning sky. It goes to the southern sky in late October, then it will never be observable again. In the Southern Hemisphere, it becomes unobservable in July. But it will appear in the evening sky at 7.5 mag in mid November. Then it keeps observable while fading gradually, although it will not locate very high.

Peculiar asteroid moving along a cometary orbit. It will approach to Sun down to 0.6 A.U. in late April. Then it will pass very near by Earth in May. The condition to observe it is very bad. Nobody can observe it until late May in the Northern Hemisphere. In the Southern Hemisphere, it will be observable in the morning low sky from late April to mid May. It will be 18.5 mag at best if it keeps asteroidal. However, if it shows cometary activity, it may be observed at 12-14 mag in the Southern Hemisphere. Then it may be visible visually at 11 mag in the evening sky in late May also in the Northern Hemisphere.

It had been lost since its discovery in 1986. But it was rediscovered on Jan. 9 at 16-17 mag. The condition is good in this return, and it was expected to reach to 14 mag from autumn to winter. But actually, it is fainter than originally expected, and it reached to 17 mag at best. Now it is 17.4 mag (Feb. 11, Mitsunori Tsumura). It will be fainter than 18 mag soon.
