* 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 4.7 mag still now (Jan. 31, Maik Meyer). 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. In the Southern Hemisphere, it will be unobservable soon.
