New Kreutz sungrazer comet discovered on the ground after 41-year blank since Comet C/1970 K1 (White-Ortiz-Bolelli). It approached nearly to the surface of the Sun on Dec. 16, and reached -4 mag or brighter at best. Then it appeared in the morning sky in the Southern Hemisphere, and it became a great comet with a bright long tail of 30-40 degrees. Now it is 8.5 mag (Jan. 6, Marco Goiato). However, the nucleus of the comet is not visible at all, fainter than 19 mag (Jan. 2, Robert McNaught). Probably the comet itself has already disappeared and only the remnant is visible. It will be fading rapidly after this. It will appear soon also in the Northern Hemisphere.

First return of a new comet which brightened up to 9.5 mag in a major outburst in 2006. It was recovered on Dec. 17, but much fainter than expected.

It reached up to 15.3 mag in early summer in 2011 (June 19, Toshiyuki Takahashi). Now it is fading. It has already faded down to 17.6 mag (Dec. 28, Hidetaka Sato). It will be fainter than 18 mag in March. I will locate high in the Southern Hemishere, but somewhat low in the Northern Hemisphere after this.

It had been fading after the perihelion passage in 2010 October, but it brightened again in outburst on Apr. 5, 2011. It reached up to 14.7 mag in May (May 28, Hidetaka Sato). It has been unobservable since July. But it is appearing in the morning sky now. Now it is 17.3 mag, much brighter than expected (Nov. 26, Hidetaka Sato). It locates low in the Southern Hemisphere. But in the Northern Hemisphere, it keeps observable in good condition after this. It will keep 17 mag for a while.

Extremely diffuse and hardly detected by CCD images. The nucleus is already fainter than 18 mag (Oct. 15, Jean-Francois Soulier). The comet can be already disintegrated. However, Juan Jose Gonzalez reported it so bright as 9.5 mag visually on Sept. 25. It is observable in good condition in the Southern Hemisphere. It locates extremely low in the Northern Hemisphere. No observations have been reported since October.

It was revealed to be a comet when appearing in the morning sky in early August. It was visible as 13.8 mag and visible visually (Sept. 4, Sandor Szabo). Now it is fading. It has already faded down to 17.6 mag (Dec. 23, G. Hug). In the Northern Hemisphere, it keeps observable in excellent condition for a long time until 2012 summer. But it will be fainter than 18 mag in late January. It is not observable at all in the Southern Hemisphere.

Now it is 15.6 mag (Dec. 17, Ken-ichi Kadota), brighter than this ephemeris. Hidetaka Sato reported a small outburst occured in early December. In the Northern Hemisphere, it keeps locating the same altitude in the morning sky. In the Southern Hemisphere, it locates extremely low now, but it will be getting higher gradually. The ephemeris says it will be fainter than 18 mag in late January. But it may keep brighter some more time.

It had expected to keep 17 mag for a long time from 2011 summer to 2012 spring and observable in good condition in the Southern Hemisphere. But actually, it has faded down to 20.7 mag (Jan. 16, D. Herald), much fainter than expected by 4 mag.
