| Abstract: | A central part of the GRB 790613 field is investigated, which contains about 1/3 of the area of 99% confidence of the GRB localization. Up to V  25 no blue optical counterparts were found. This can be interpreted as the absence in the field of single compact objects of the neutron star type as a possible potential source of  -burst, up to a distance of 30 pc. |
