New comet discovered on Feb. 11. It was very bright as 10.6 mag (Feb. 12, A. Novichonok, V. Gerke). However, the comet is getting diffuse and fading rapidly after Feb. 20. It was still visible visually at 12.5 mag on Feb. 21 (Alan Hale). But it became completely invisible on Feb. 27 (Hidetaka Sato). The nuclear magnitude is fainter than 19 mag. It will approach to the sun down to 0.8 A.U. in mid March, but maybe it has been already disintegrated. It is already unobservable in the Southern Hemisphere. In the Northern Hemisphere, it keeps observable until mid March, although it will be getting lower in the evening sky. The comet has approached to the earth down to 0.2 A.U. in late January. Then it must have located in excellent position, but it has not been discovered.

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 12.0 mag (Jan. 27, Alan Hale). 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. The tail became extremely faint, but the long tail of 2 degrees is detectable by photos still now with an excellent sky condition (Feb. 21, Lester Barnes). Now it is observable also in the Northern Hemisphere.

First return of a new comet which brightened up to 9.5 mag in a major outburst in 2006. The condition is excellent. It keeps very close from the earth. It brightened up to 13.5 mag in late December (Dec. 26, Michael Jager). But it looks extremely diffuse. It is bright as 16.3 mag still on Feb. 12 (Mitsunori Tsumura). It will keep close to the earth and observable in good condition in the evening sky for a while after this. However, it may fade out very rapidly after this.
