History

This planetary nebula was discovered in 1955 by the American astronomer George Ogden Abell on the photo plates of the «Palomar Observatory Sky Survey» (POSS). In 1955 he published a first list of 13 globular clusters and the positions of 73 planetary nebulae. The PN had the number 19 (A55 14). In 1966 Abell published a complete list including the size and description of the 86 planetary nebulae discovered on the POSS photo plates. This planetary nebula was then number 19 on his list. [331, 332]

The designation PK 200+08.1 comes from the two Czechoslovak astronomers Luboš Perek and Luboš Kohoutek, who in 1967 compiled a catalog of all the planetary nebulae of the Milky Way known at that time. [146]

The lesser known designation ARO 130 originates from 1971 survey of microwave radiation from planetary nebulae conducted by Canadian radioastronomer Lloyd A. Higgs using the 46-metre Algonquin Radio Observatory in Ontario, Canada. [136, 137]
