## [31.17] On The Nature of Faint Galaxies with Strong UV Excess

Four faint galaxies identified in the Case Low-Dispersion Northern Sky Survey (Stephenson, Pesch, MacConnell 1992,ApJSS,82,471) show unusually strong UV excess in their objective prism spectra. We are currently investigating the nature of these galaxies (CG 1280, CG 1293, CG 1298, CG 1331). The preliminary results from the analysis of the spectra for galaxies CG 1293 $(R.A.=15^{h}22^{m}00^{s}.0, Decl.=+30\deg 29^{'}.7 [1950])$ and CG 1331 $(R.A.=15^{h}54^{m}41^{s}.9, Decl.=+29\deg 57^{'}.4 [1950])$ are presented. Stephenson, Pesch and MacConnell report that both galaxies have blue magnitudes of approximately 17. We obtained observations of these objects on 1992 July 2 and 3 with the CCD spectrograph on the 40-inch telescope at Mount Laguna Observatory. This CCD has an 800 x 800 format and covers an approximate wavelength range of $4000\AA$ to $7000\AA$. Our analysis of the spectra reveals strong $H\alpha$ emission with broad line profiles characteristic of Seyfert 1 galaxies. The spectrum of CG 1293 indicates a redshift of z = $0.1255 \pm 0.0003$ and an $H\alpha$ emission line width of 4180 km/sec (FWHM). The [SII] pair $\lambda 6717$ and $\lambda 6731$ have also been identified. We have determined a preliminary redshift for CG 1331 of z = $0.089 \pm 0.004$. The $H\alpha$ emission line width for CG 1331 is 7350 km/sec (FWHM). Lines corresponding to $H\beta$ and $H\gamma$ have also been identified.
