The comet showed another outburst recently on February 11, 2022. It was drifting slowly toward southeast through dust-rich area in Taurus. Direction and velocity of the drifting changed. The round-shaped dust area got fainter and more expanded than before. The color looked bluish white as before. The density was lower toward northwest like an indentation mark as before. There looked to be far smaller round-shaped dust area inside. It must be made of fresh dust scattered during the recent outburst. There looked to be L-shaped jet-like structure near the center again. North is up, and east is to the left.
