This barred spiral Sbc(s)II galaxy is notable for how well the H II regions
delineate the bar, inner ring, and almost the entire length of each of its
half-dozen or so arms, "like beads on a necklace" to paraphrase Baade
(1963). The two major arms appear to be extensions of the bar, which leads
to the impression that they intersect perpendicularly with the inner ring of
H II regions. It is the home of supernova SN1982R which brightened to a max
of magnitude 14.6 on Oct 6, 1982.(Distance: 58 million ly)
