Arp 161 is the first member of the class Diffuse Filaments.
I would have put it in the earlier listed class Material Emanating from E
Galaxies, but that is just a visual opinion from an image. The Atlas note
is also a little puzzling, saying "faint, diffuse material extends away from
neck." I see nothing that looks like a neck. It makes me suspect
that there was some reorganization of the manuscript and this class and note were
intended to apply to a different galaxy.
This is another image taken at the Texas Star Party, in 2006.
