Descripción
We report on near-infrared and optical observations of the GRB 970616
error box and of the X-ray sources discovered by ASCA and ROSAT in the
region. No optical transient was found either within the IPN band or in
the X-ray error boxes, similarly to other bursts, and we suggest that
either considerable intrinsic absorption was present (like GRB 970828)
or that the optical transient displayed a very fast decline (like GRB
980326 and GRB 980519). Based on observations collected at the
German-Spanish Astronomical Centre, Calar Alto, operated by the
Max-Planck-Institut für Astronomie, Heidelberg, jointly with the
Spanish National Commission for Astronomy.Based on observations carried
out at the Danish 1.54-m Telescope on the European Southern Observatory,
La Silla, Chile.
