The comet NEAT in that day is lying in the constellation of Ursa Major. The brightness of coma became down to about 5th magnitude, but the comet has an ion tail with 4 degrees in length stretched to east and a fan-like dust tail stretched from east to south. The comet showed us an interesting V-shape, I could still enjoy the splendid view of the comet.
