RCW 24
Emission Nebula, Puppis
RCW 24 is a small HII region located in the constellation Puppis.
The RCW Catalog (from Rodgers, Campbell & Whiteoak) is an astronomical catalog of Hα-emission regions in the southern Milky Way. It contains 182 objects, including many of the earlier Gum catalogue (84 items) objects. The later Caldwell catalogue included some objects from the RCW catalogue. There is also some overlap with the Sharpless catalogue-2 (312 items), although that primarily covered the northern hemisphere, whereas RCW and Gum primarily covered the southern hemisphere. 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.
