Aperture synthesis observations of Orion B at 2.695 and 8.085 GHzInterferometer observations of Orion B at 2.695 and 8.085 GHz are presented. Orion B appears to be a double source: one H II region associated with the star NGC 2024 No. 2 and an extended H II region surrounding the star NGC 2024 No. 1. This structure gives support to the model that the stars NGC 2024 No. 2 and No. 1 (of spectral type O 9.5 and B 0.5, respectively) ionize the nebula.
