Abstract:

The results of the follow-up spectroscopy of 187 emission-line galaxy (ELG) candidates from the Case objective-prism survey with the 6m telescope are described. Only the candidates classified in the Case survey as those with emission lines were observed with the aim to form a statistical sample of blue compact galaxies (BCGs) with strong emission lines in the zone $\alpha$ = 8^h - 16^h, and $\delta$ = +29$^{\circ}$ - +38$^{\circ}$.We present the redshifts, equivalent widths and flux ratios for the strongest lines and the spectrum type for the most of galaxies with detected emission lines. Significant fraction ($\sim$ 23%) of the observed Case galaxies do not show emission lines in blue. Preliminary analysis of the data is presented and the properties of the observed ELGs are compared with those of other known samples.
