Scientific paper

Near infrared speckle observations have shown the nearby M5.5e dwarf Gliese 866 (= L 789-6 = LHS 68) to have a companion of similar colour. The brightness difference at 2.2 μm was 0.55±0.07 mag, the projected separation 0arcsec.39±0arcsec.02 at a position angle of 0°±5°, corresponding to 1.3 AU at the distance of the object.
