Optical positions of seventeen radio stars from circumzenithal observations by the method of equal altitudes.
Positions and proper motions of seventeen radio stars were improved from observations by the method of equal altitudes as performed by circumzenithals in Prague, Pecny and Bratislava during 1980-1994. Average accuracy of right ascensions, declinations and their proper motions is 0.004s, 0.04", 0.001s.yr^-1^ and 0.01".yr^-1^, respectively.
