New Kreutz sungrazer comet discovered from the spacecraft images. Terry Lovejoy succeeded to catch the comet on the ground on Mar. 10 at 9.2 mag. It will appear in the evening sky in late March in calculation. But actually, the comet must have evaporated at the perihelion passage on Mar. 15.

New comet discovered on Feb. 11. It was very bright as 10.6 mag (Feb. 12, A. Novichonok, V. Gerke). However, the comet got diffuse and faded 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 must have been disintegrated before the perihelion. It is not observable now.

Big asteroid discovered in 1906. It suddenly showed the cometary activity on Dec. 11, 2010, probably due to an impact of a small object. It was very bright as 11.5 mag visually (Dec. 17, 2010, Juan Jose Gonzalez). Now it is 14.1 mag (Jan. 3, Hidetaka Sato). It has already turned to be stellar.

It is expected to be bright as 9 mag from 2012 to 2013. It is already so bright as 11.7 mag and visible visually (Mar. 22, Carlos Labordena). In the Northern Hemisphere, it keeps observable in good condition for a long time until 2012 autumn when the comet brightens up to 10 mag. In the Southern Hemisphere, it is hardly observble before the perihelion passage. But it becomes observable in good condition since 2013 after the perihelion passage.

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. However, the nucleus of the comet was 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 detectable by photos still now with an excellent sky condition (Mar. 12, Lester Barnes).

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 was 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 can have already faded rapidly.
