Journal Article

· Publ. Astron. Soc. Pac.; (United States)
The nebula NGC 2242 is found to be a previously unknown planetary nebula. Its emission-line fluxes and a finding chart are presented. The nebula is found to have very high ionization and high temperature (Te = 25,000 K). The oxygen/hydrogen abundance ratio, derived by assuming a constant argon/oxygen ratio, is rather low (O/H = 0.00008) and is consistent with the high electron temperature. 12 references.
