摘要：

Surface photometry of the nebulosity surrounding the x-ray selected BL Lacertae object H0414 + 00 is presented. The radial profile is consistent with a giant elliptical galaxy of M(v) = - 23.2. Simultaneous optical to IR observations at three different epochs show wavelength dependent variability. The spectral flux distribution is interpreted in terms of a galaxian contribution superposed onto a flat (alpha-nu approximately 0.3), variable nonthermal component.
