Scientific paper

Late-time observations of GRB970508 with the SAO-RAS 6-m telescope in July-August 1998 show that the optical transient (OT) varies very little since November 1997. Here we report the BVRI light curves behaviour up to 470 days from the GRB occurence with independent B, V, R, I power-law fits. After 200 days the power-law decay has ceased and the OT contaminations to the host galaxy flux is already less than the observational errors of the brightness estimates. Spectral energy distribution for the host galaxy alone (without OT) and comparision of its broad-band spectrum to the average continuum spectra of different Hubble types galaxies are shown. The best fits the BVRI spectral energy distribution of the GRB host with local star-forming galaxies are found for the Scd starburst HII galaxy NGC7793 and the blue compact galaxy Mrk 1267. The normal galaxies with types earlier than Sbc are confidently excluded.
