ASTRO: A Serendipitous discovery

I've had several two fer images for Arp galaxies, now it is a two fer
for Arp-like galaxies. One I imaged intentionally, the other snuck in
unannounced.

NGC 6339 is a SBd barred spiral galaxy in Hercules about 2.3 degrees due
south of M92. It is about 100 light-years distant. I put it in my
Arp-like category due to the very different arms. The eastern arm that
comes off the bar has two nice narrow streams of young blue hot stars
and a short segment of a third all running parallel to each other though
apparently not connected to the bar. The western arm is a single rather
diffuse arm consisting of much older, longer lived stars though it too
has a outer region of super hot blue stars. The bar itself seems
unsymmetrical assuming the brightest knot is the core. If so most of
the bar is east of the core. A very odd situation. It appears to have
a very red companion well off the northern arm to the northeast. This
near edge on spiral has a dust lane same as a normal blue spiral seen
edge on. It is MCG +07-35-062. Like nearly all the thousand+ galaxies
in this image it has no redshift data. Is it a true companion or just a
foreground or background galaxy? I found nothing useful on this.

Then serendipity struck:
I was about to call this one as not as interesting as I thought but then
upon processing the image CGCG 225-097 at 380 million light-years got my
attention at the bottom of the image. It has one heck of an odd plume
running mostly north south at a steep angle to the disk of the galaxy.
This too would seem to be a worthy Arp galaxy. Is this a polar ring
galaxy in the making? If so where's the material feeding the ring
coming from? I found no papers on this odd ball of a galaxy. Looks to
be a spindle galaxy with an odd plume. Or is it another galaxy hiding
behind the galaxy's disk? NED shows it as being only one galaxy
however. Anyone know of any papers on this strange object?

With only two galaxies having redshift data I didn't prepare an
annotated image.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Rick,

what a beautiful barred spiral. I don't think I have seen this one before,
might be because it is very faint.
