Optical observations in the field of GRB 970111

Abstract

B, V and R optical photometry performed on the field of the GRB 970111 soon after its detection by BeppoSAX is presented. No remarkable optical object is found inside the corrected error box. The optical counterpart of an X-ray and radio source and a suspected red variable (probably an eclipsing binary) have been detected inside the field of GRB 970111.
