* 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 6.3 mag still now (Mar. 20, 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.

Now it is bright as 9.5 mag (Mar. 22, Marco Goiato). In the Southern Hemisphere, it will be getting higher gradually after this. In the Northern Hemisphere, it keeps extremely low and hard to observe until June. It will be observable in good condition after June while the comet will be fading gradually.

* 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. Now it is fading. It has already faded down to 14.7 mag (Mar. 18, Sandor Szabo). 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.
