SEARCH FOR AN OPTICAL COUNTERPART OF THE SOURCE OF GRB-911001

The positional error box of GRB 911001 is centered in the north eclipt ic pole field (Fishman et al. 1994) which was extensively observed wit h the Tautenburg Schmidt telescope between 1990 and 1992 (more than 10 0 Schmidt plates). The plate taken nearest to the time after the occur rence of the burst is from 1991 October 2. We report here on the resul ts of a search for variable objects within the error box of GRB 911001 . We detected four objects, among them a possibly so far unknown catac lysmic variable. At the time of the occurrence of the GRB this object was presumably in a maximum state.
