Optical nebulosity has been found coincident with the nonthermal radio source G292.0+1.8. The radio properties of the source are like those of other filled-center supernova remnants. It is the third such supernova remnant discovered in the optical. The spectrum of the nebulosity shows forbidden lines of oxygen and neon, but no Balmer lines. Interstellar reddening of the nebulosity is small, E(B-V) about 0.9 mag, and its temperature high, about 36,000 K. The data suggest that G292.0+1.8 is the remnant of a comparatively recent supernova of a massive star (about 20 solar masses).
