I noticed that the coma is asymmetrical around the nucleus and predominates to its right side of the photo (not referring to the obvious elongation of the tail). What do you think causes that effect?
Also, I couldn't help notice the bluish component in the tail (possibly at an angle to the main tail). Is that due to the ionization effect seen in some of the other comets like Hale-Bopp?
It seems that the comet's progress across the constellations appears to be accelerating and even is noticeable at high power now.
I really enjoy your timely photos.

Configuration of comet wrt to sun and earth. Line of sight effect when looking at a comet tail obliquely

Thanks Tony & Cames - here's a concecutive 3x30s stack showing rapid motion SW eg lower rightThanks for posting, Maurice.I noticed that the coma is asymmetrical around the nucleus and predominates to its right side of the photo (not referring to the obvious elongation of the tail).

Regarding the ionization effect seen on comets: Is it the result of the solar wind interacting with cometary effluvia; and the light emission a product of excitation phenomena similar to our aurorae?

Dire conditions continue and first clearish night this week with comet recorded tonight through thin cloud. Comet now in TaurusA most fascinating apparition if you ask me.Regarding the ionization effect seen on comets: Is it the result of the solar wind interacting with cometary effluvia; and the light emission a product of excitation phenomena similar to our aurorae?------C

According to Wikipedia,and some other online information, ionization of the tail occurs through UV photons, not through collisions with solar wind particles.
