  Since this is a gama object; what do we have here?

  Everything looks so blue in GAMA-KiDS, because images are only in two colours, blue and red (cyan and amber)

  3 choices?

  Either a bar with a resonance ring, though it is not symmetrical Forum: Ringed and Pseudoringed Galaxies EricFDiaz http://www.galaxyzooforum.org/index.php?topic=10635.0 The Kinematics and Dynamics of Galactic Rings, The Physics of Resonance

  Or a debris trail from an old collision or flyby. Maybe that galaxy on the right. 2.8 Galaxy Mergers and Flybys and Merger Zoo https://talk.galaxyzoo.org/#/boards/BGZ0000001/discussions/DGZ0000wrb?page=2

  Nearly a collisional ring, but the center was not removed. 2.4 Ring galaxy (empty in the middle) collisional ring galaxy - created by collision that removed the inside of the galaxy) https://talk.galaxyzoo.org/#/boards/BGZ0000001/discussions/DGZ0000wrb?page=2 I'll put it in there.
