Its nucleus is off-centre and it is surrounded by a bright ring of HII regions where new stars are formed.
One fainter outer ring or shell also hosts a faint arc of HII regions.
[2] The hydrogen emission of the galaxy shows a large disturbed hydrogen disk extending for 2.7 times the optical diameter of the galaxy and features shells.
[4] The mid-infrared emission is associated with the nucleus and the star forming regions of the ring.
