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.
