Arp 316 is in the Galaxy Groups class. The Atlas note is "edge-on spiral
shows signs of interaction".
All three large galaxies make up Arp 316. Within Arp 316, the
integral sign spiral is
NGC 3187, the nearly edge-on spiral is NGC 3190, and the E-like galaxy at the NE
apex of
the triangle is NGC 3193. The dust lane in NGC 3190 is a strong one. Both
3190 and 3187 show obvious evidence of interaction. On close
inspection, this image shows a wide band of material connecting 3193 and
3190, and a narrower U-shaped band from the SW end of 3187 to the S side
of 3190. NGC 3185, the spiral in
the lower right corner, is not part of the Arp group but is an
interesting galaxy. It has an extremely faint yellowish halo twice the
diameter of the bright part of the galaxy. There are many more galaxies in the field. Four of the more
interesting are the clumpy irregular SDSS_J101832.71+215236.4 about 2'
SE of 3193, the tiny edge-on 2MASXJ10181187+2151294 between 3193 and
3190, 2MASXJ10174317+2150588 on the SW tip of 3187, and LSBC D500-05
about 20% of the way up from the bottom and just E (left) of center.
