Nick,I realised that the 3i anti-tail we are seeing is not the “usual” type of comet anti-tail that we see in LP comets which lay a trial of dust along the orbit, which we can then see edge on as we cross the orbital plane of the comet.In 3i we are seeing dust that is being released at present but remaining in the direction of ejection.
Is that correct?
I am here to learn that is why I am in the BAA.
