Abstract

Positions and proper motions of seventeen radio stars were improved from observations by the method of equal altitudes as performed by circumzenithals in Prague, Pecný and Bratislava during 1980–1994. Average accuracy of right ascensions, declinations and their proper motions is , , and , respectively.
