The Sixth European Regional Meeting in Astronomy (VI ERMA) on "Sun and Planetary System" was held in Dubrovnik (Yugoslavia), 19-23 October 1981, sponsored by the Federal Executive Council of Yugoslavia, the IAU, IUGG, and the European Physical Society. The Scientific Organizing Committee included W. Fricke (Chairman), H. Alfven, H. Haupt, H. Kautzleben, Z. Kopal, J. Kovalevsky, V. A. Krat, L. Kresak, G. Marx, P. Melchior, P. J. Message, J. -C. Pecker, G. Sitarski, B. Sevarlic, G. Teleki, and R. M. West. The Local Organizing Committee representing the Union of Societies of Mathematicians, Physicists and Astronomers, Yugoslavia, included G. Teleki (Chairman), I. Pakvor (Vice-Chairman), Z. Knezevic (Secretary), B. Jovanovic, L. Randic, P. Ranzinger, V. Ruzdjak, B. Popovic, and B. Sevarlic. The Meeting was attended by 216 participants from 27 countries (5 continents). The scientific programme was divided into the following five sections: (1) Sun from the astronomical and physical points of view (main organizer: J. -C. Pecker); (2) Astronomical, geophysical and geodetic problems related to the Earth (main organizer: J. Kovalevsky); (3) Physics of planets, minor planets, satellites and interplanetary medium (main organizer: Z. Kopal); (4) Motions in the planetary system (main organizer: L. Kresak); (5) Three dimensional refraction (main organizer: G. Teleki). Ten invited review papers were presented in 5 plenary sessions; 20 invited papers and about 100 contributed papers were presented in parallel sessions.
