* C/2014 Q2 ( Lovejoy )

It brightened up to 3.7 mag and became a naked eye comet in mid January (Jan. 13, Marek Biely). Now it is fading. But it is bright as 6.4 mag still now (Mar. 25, Carlos Labordena). In the Northern Hemisphere, it keeps observable all night until July when the comet will fade down to 13 mag. It is not observable in the Southern Hemisphere.
