Scientific paper

Speckle observations of the spectroscopic binary star 94 Aqr A are analyzed in order to determine the Aa,b system visual orbit. Eleven angular separation and position angle observations yield orbital elements which are in agreement with those obtained by Sarma (1961) spectroscopically, and which in combination with the trigonometric parallax of 0.033 arcsec yield Aa and Ab component masses of 3.0 and 1.2 solar masses, and absolute magnitudes of +3.1 and +4.6, respectively.
