P. ; Filippenko, A. V. Abstract Optical spectrophotometry of the nearby Seyfert 1 galaxy NGC 7213 reveals that nonstellar radiation accounts for at least 50% of the observed continuum at 位3300. A formal decomposition of the continuum into a power law of index 1.1 and the spectrum of a giant elliptical galaxy suggests that the true nonstellar flux may be substantially larger if reddening is allowed. X-ray spectra obtained with the IPC and MPC on the Einstein Observatory are also presented. Published observations at radio, IR, and UV wavelengths are combined with the new data to produce the overall continuum, which is similar to that of other type 1 Seyfert galaxies.
