* C/2012 X1 ( LINEAR )

It brightened rapidly in outburst in mid October. Now it is bright as 7.8 mag (Feb. 22, Maik Meyer). It keeps 8-9 mag for a long time until early summer, and it keeps observable in the morning sky in the Northern Hemisphere. In the Southern Hemisphere, it is getting higher and it will be observable in excellent condition after spring.

* C/2013 R1 ( Lovejoy )

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 8.0 mag (Feb. 22, Maik Meyer). In the Northern Hemisphere, it keeps observable in excellent condition for a long time until 2014 autumn when the comet will fade out. It is appearing in the morning sky again also in the Southern Hemisphere, and it keeps observable in good condition after this.

* C/2014 C2 ( STEREO )

New bright comet discovered in the STEREO spacecraft images. It brightened up to 3.8 mag on Jan. 31 thanks to the forward scattering. It was observed at 15.2 mag on the ground (Feb. 20, Hidetaka Sato). It approached to the Sun down to 0.5 a.u. on Feb. 18. Because the absolute magnitude is faint as 18 mag, it may be disintegrated. It is appearing in the morning sky in the Northern Hemispehre. In the Southern Hemispehre, it will not observable after this. But it must have been observable in excellent condition in 2013. Colin Drescher reported the comet was visible on SWAN images for several days in late December at about 11 mag.
