Adaptively smoothed X-ray image with V-band contours from WINGS (Fasano et al. 2006) in green. The distance of the “Comet” from the cluster center (Z8338) is 5.3′ (310 kpc). The tail of the “Comet” has roughly a length of 1.3′ (76 kpc). Two close member galaxies (CGCG254-021 and J181025.63) are labeled as well; we assume that the comet-shaped X-ray emission is due to gas stripped from CGCG254-021.
