We report on pulsational variability found in our decade-long study of UV and optical RV, light, K-line data sets for α Ori, α Sco A, and α Her A. As summarized by Smith et al. (1990), our radial velocities are derived from McMath observations of five metallic lines near Hα plus Hα itself. Optical light curves were obtained by small photometric telescopes, and K-line emissions from the Mt. Wilson K-line project. UV continua at 3000Å and k/h emission indices were obtained with the IUE LWP camera.
