This member has a Seyfert 2 nucleus with extra-planar features emitting H-alpha radiation. There are filamentary features on each side of the disk, including a jet-like structure extending about 4 kpc in the NE direction. It may have lost its neutral hydrogen (H1) gas due to interactions with the other members of the clusters—most likely NGC 92.[4]
