GUM 39

Gum39 -This bright nebula is centred around the O6 V HD 99897 star and corresponds to the "body" of the Running Chicken nebula complex.

The Gum catalog is an astronomical catalog of 84 emission nebulae in the southern sky. It was made by the Australian astronomer Colin Stanley Gum (1924-1960) at Mount Stromlo Observatory using wide field photography.

Gum published his findings in 1955 in a study entitled A study of diffuse southern H-alpha nebulae which presented a catalog of 84 nebulae or nebular complexes.
