(meteorobs) Birth of a debris stream

[Chris Peterson]

The axis of the structure, as well as the faint tail or jets that have 
been caught in a few images, is at about 200°. I haven't worked out the 
projection of the comets antisolar point from our view, but graphically 
that looks about right.

I haven't really made the suggestion that this is either a tail or 
trail, only that it represents some sort of debris stream. From a comet, 
debris can either be largely co-orbiting, which I guess is what you'd 
call a trail, or driven by solar wind into a significantly different 
orbit, which I guess you'd call a tail. I'd expect the bigger pieces to 
be more trail-like, and the fine dust to be in a tail.

The coma is also very transparent, so the structure I imaged may not 
even be inside it at all, but could be a foreshortened view of the tail 
extending backwards as seen through the coma.
