Valencia), report on behalf of a larger collaboration:\n\n\"We have  carried out R-band  observations of the GRB100316  BAT error\nbox (Baumgartner et  al., GCN 10484) with the  1.23m telescope of Calar\nAlto.  The observations started on  Feb 16.1075 UT (11.7 min after the\nGRB).  We detect an object with a rough magnitude of R~20.5 coincident\nwith the  XRT (GCN 10485) position and  very likely  not  present on  the \nDSS.   Further observations  are   encouraged  to  determine   the \npossible  fading behaviour  of this  source.  We  propose  that object  as\nthe potential optical afterglow of GRB100316.\"",
