I dug up old data before COVID-19 era again.

I like those dark clouds in the upper half.

Imagine a running moose and a following fox in the winter field.
I found them in 2009. A chubby boar is also following them:

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.

This image is part of my mosaic Clouds of Orion, to which I added H-alpha data from John Gleason, that gave the whole image a rich bath of red from all those hydrogen clouds glowing all over the place.
