Abstract: New (2011–2015) observational data, got at speckle-interferometer of 6m BTA SAO RAS telescope, led us to improve orbital solution for HD 76644. Orbit seems to be more circular and it's eccentricity affects critically at system's dynamical stability – new solution more stable than all previous attempts.
