It passed only 0.4 A.U. from the earth, and 0.8 A.U. from the sun in November and December, and brightened up to 4.7 mag (Nov. 28, Juan Jose Gonzalez). Now it is 5.4 mag (Dec. 20, Yoshimi Nagai). In the Northern Hemisphere, it keeps observable in excellent condition for a long time until 2014 autumn when the comet will fade out. In the Southern Hemisphere, it is not be observable from mid November to early February.

Although it was predicted to be 14 mag, it brightened up to 8 mag in outburst in mid October. It is bright as 9.3 mag still now (Dec. 16, Marek Biely). Mitsunori Tsumura reported the comet got active again in December.It will be observable in excellent condition in 2014 spring. In the Northern Hemisphere, it will be getting higher gradually in the morning sky. In the Southern Hemisphere, it is not observable until 2014 February.

It was expected to be a great comet as it approached to the sun down to only 0.01 A.U. on Nov. 28. It brightened up to -2.5 mag at best. However, the comet's nucleus disrupted at the perihelion passage. After that, the dust remnant had been visible until Dec. 6 on the STEREO spacecraft images. However, the dust remnant has not been detected by CCD observations on the ground. The nucleus is not detected, fainter than 18 mag (Dec. 13, Lorenzo Comolli). But visual observers reported it was visible at 7.5 mag on Dec. 6 (Piotr Guzik), 7.2 mag on Dec. 7 (Juan Jose Gonzalez), and 9.6 mag on Dec. 9 (Jakub Cerny). It approaches to the earth down to 0.4 A.U. from mid December to early January. It will be observable in excellent condition in the Northern Hemisphere, but it is extremely hard to catch the comet. It is not observable in the Southern Hemisphere.
