  The observations with the SAO-RAS 6-m telescope in July-August 1998 show that
the GRB970508 optical remnant has varied very little since November 1997. We
can conclude that we observe a proper host galaxy without the GRB optical
remnant. The fitting results of the light curve of the GRB remnant plus the
host galaxy until about 400 days after the primary event are reported here. The
best $\chi^2$-fits with a power law, for most of the filters used, are not
acceptable. Some intrinsic variability of the GRB optical remnant fading is
possible, which demands a more complex law presenting the largest multiband
homogeneous data set from a single telescope.
