A large, face-on disk following a distracting 8th mag. star. Round apart from a missing segment in SE quadrant. Illumination is even across the disk with no core or nucleus. There appear to be subtle dark lanes which hint at a Catherine Wheel appearance. In the drawing ARP 25 is on the left and is one half of ARP 114.
