Spectrum of the halo surrounding the quasar PHL 1070

The quasar PHL 1070 and its surrounding halo of light were observed with the Palomar multichannel spectrophotometer by using circular and annular apertures. The central quasar has a magnitude m/sub v/ = 16.6 and an emission line redshift of z/sub em/ = 0.076 +- 0.002. The halo light has a magnitude m/sub v/ = 19.0 and a possible absorption line system with redshift z/sub abs/ = 0.067 +- 0.008. The magnitude, possible absorption lines, and probable spectral energy distribution of the halo are consistent with those of a normal galaxy at the redshift of the quasar. 1 figure, 3 tables
