Group? Merger?

• by nyjtm

  How would others classify these objects? Are they merging? In a tight group? Other?

  The two galaxies have consistent redshifts (z=0.118), but I don't see any signs of tidal debris or disturbing their morphologies yet (which is unusual, given how closely they're approaching each other).

  They're definitely in the same galaxy group; I'd probably classify it as a merger with no sign of tidal debris.
