RCW 32, also known as Gum 15, is about 3,000 light-years away in the constellation of Vela. The bright star near the center of the nebula is HD 74804 a 9.26 magnitude star, spectral type B3/5II D. The central region shows dark areas of dust, with some faint reflection structures crossing it. This emission nebula is part of a larger HII region, located just 1.5 degrees North of the Vela Supernova Remnant. The RCW Catalogue (from Rodgers, Campbell & Whiteoak) is an astronomical catalogue of Hα-emission regions in the southern Milky Way, described in (Rodgers et al. 1960). It contains 182 objects, including many of the earlier Gum catalogue (84 items) objects. The RCW catalogue was compiled by Alexander William Rodgers, Colin T. Campbell and John Bartlett Whiteoak. They catalogued southern nebulae while working under Bart Bok at the Mount Stromlo Observatory in Australia in the 1960s.
