Scientific paper

The SBb(s) spiral NGC 6872 is characterized by a bright nucleus and two very extensive spiral arms. At a redshift distance of 92 Mpc (corresponding to H = 50 km per sec per Mpc), the projected size (to sigma equal to 25.5 B mag/arcsec squared) from the tip of one spiral arm to the other is approximately 8 arcmin, or 214 kpc. The extent of the arms is probably greater than in any other spiral known; it is concluded that NGC 6872 is a conventional barred spiral in which severe tidal interaction took place.
