* C/2014 Q2 ( Lovejoy )

It brightened up to 3.7 mag and became a naked eye comet in mid January (Jan. 13, Marek Biely). It is bright as 5.5 mag still now (Feb. 28, Maik Meyer). It kept brightening even after the perihelion passage. However, it will be getting fainter gradually after this. In the Northern Hemisphere, it keeps observable in good condition after this until the comet fades out. It is not observable in the Southern Hemisphere.

* C/2013 A1 ( Siding Spring )

The brightness evolution has slowed down before the perihelion passage, and it faded down to 11.6 mag in late October (Oct. 26, Todd Augustyniak). However, an outburst occured around Nov. 10-12, and it brightened by 2 mag. It is bright as 11.7 mag still now (Feb. 16, Jakub Cerny). In the Northern Hemisphere, it will be observable in excellent condition after this while the comet will be fading. It is observable in the morning low sky until early April also in the Southern Hemisphere.
