* C/2013 R1 ( Lovejoy )

Now it is so bright as 4.9 mag (Dec. 4, Jakub Cerny). It will pass only 0.4 A.U. from the earth, and 0.8 A.U. from the sun in November and December, and will brighten up to 4-5 mag. 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.

* C/2012 S1 ( ISON )

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. It faded down to 5 mag on Nov. 30 after the perihelion passage. In the Northern Hemisphere, it is appearing in the morning sky again. Piotr Guzik and Juan Jose Gonzalez observed the comet's remnant as 7.2-7.5 mag on Dec. 6-7. It approaches to the earth down to 0.4 A.U. from mid December to early January, and it will be observable in excellent condition in the Northern Hemisphere. Probably the dust remnant will be visible around 8-9 mag. It is not observable in the Southern Hemisphere.

* C/2012 X1 ( LINEAR )

Although it was predicted to be 14 mag, it brightened up to 8 mag in outburst in mid October. The dust shell is getting diffuse after that, and expanding up to 50x20 arcmin (Nov. 28, Michael Jager). Now it is bright as 9.3 mag (Dec. 5, Jakub Cerny). 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.
