perfect image Paul,
I tried to find evidence elsewhere of some other structure in the halo.
All I could find was here:

but it's not a nice large image.

Figure 5. Even well-known galaxies can spring surprises. This deep image of M83 reveals an enormous loop around the NW quadrant of the galaxy. The inset image is the same scale as the main picture. The scale bar is 30 arc min.
