J.  Gorosabel  (IAA-CSIC/UPV-EHU),  S.  Mottola (DLR),  A.  de  Ugarte Postigo  (IAA-CSIC/DARK-NBI),  S.  Hellmich  (DLR), G.  Proffe  (DLR), report on behalf of a large collaboration:

We imaged the  field of GRB 131108A (Racusin et  al.  GCNC 15464) with the 1.23m  CAHA telescope.  The  observations were carried out  in the V-band starting at  03:28:33 UT.  A bright V~18.5 object not present on the DSS is  detected consistent  with the  possible X-ray afterglow  position (Stroh & Kennea, GCNC 15468). Further observations are in progress.
