We present UBVRIZJsHKs broad band photometry of the host
galaxy of the dark gamma-ray burst (GRB) of February 10, 2000.
These observations represent the most exhaustive photometry given to
date of any GRB host galaxy. A grid of spectral templates have been
fitted to the Spectral Energy Distribution (SED) of the host. The
derived photometric redshift is , which
is in excellent agreement with the spectroscopic redshift
(
) proposed by Piro et al. ([CITE])
based on a single emission line. Furthermore, we have determined
the photometric redshift of all the galaxies in an area of
around the host galaxy, in order to
check for their overdensity in the environment of the host. We find
that the GRB 000210 host galaxy is a subluminous galaxy (
), with no companions above our detection
threshold of
. Based on the restframe
ultraviolet flux a star formation rate of
yr-1 is estimated. The best fit to the SED is obtained for a
starburst template with an age of
Gyr and
a very low extinction (
). We discuss the
implications of the inferred low value of AV and the age of
the dominant stellar population for the non-detection of the
GRB 000210 optical afterglow.
