NGC 5367

NGC 5367 is a reflection nebula in the constellation Centaur. It was discovered on June 26, 1834 by John Herschel with an 18-inch reflecting telescope, who noted in several observations:

„a close double star in a very large, bright, luminous atmosphere, 2′ diameter. The star A which is quite as bright, has no such atmosphere. The atmosphere is very little brighter in the middle. The star was not noticed as double till too late for a good measure after I showed the object to my attendant J.S., verified with 240x and 320x. A furious hot north wind, but the definition of stars excellent. It is no illusion, other stars are sharp and brilliant, and have not the least nebulous appearance“

„double star h 4636 involved in nebulosity“

„the nebulosity is very evident ... neb at least 2′ or 2.5′ diameter“

„very faint, 2′ diameter, and star of 9th mag following, is about 4′ distant, is unaffected with nebulosity“.

In his notes we find:

„NGC 5367 and NGC 1847 are nebulae, centrally involving double stars. Central superposition must undoubtedly be held strong presumptive evidence of physical connexion“.

Lewis A. Swift also observed this nebula on December 30, 1897, this found an entry in the index catalog as IC 4347.
