New bright comet discovered in the STEREO spacecraft images. It brightened up to 3.8 mag on Jan. 31 thanks to the forward scattering. It was observed at 15.2 mag on the ground (Feb. 20, Hidetaka Sato). It approached to the Sun down to 0.5 a.u. on Feb. 18. Because the absolute magnitude is faint as 18 mag, it may be disintegrated. It is appearing in the morning sky in the Northern Hemispehre. In the Southern Hemispehre, it will not observable after this. Colin Drescher reported the comet was visible on SWAN images for several days in late December at about 11 mag.
