Martin Jelinek,  Alberto J. Castro-Tirado,  Javier Gorosabel
(IAA-CSIC Granada)  and  R. Piontek (AIP Potsdam)  report on
behalf of larger collaboration:

We   observed  the  Swift-BAT  errorbox  of   a  GRB  071008
(trigger=293587, Moretti et al., GCN 6856), with an IAC 80cm
telescope at La Palma starting at  05:43 UT  (7.8h after the
GRB). Our 3 x 180s  combined  R-band  image has  a  limiting
magnitude of R < 21.5  and does  not show any  new source in
comparison to a DSS-Red, implying  a DSS-equivalent limit to
the afterglow detection.
