... observations of the releases of barium vapor on 2 successive days indicated that a pulsating aurora was induced by vapor releases near 250 km altitude, but only when the explosions occurred in the path of precipitating electrons associated with the visible aurora. Previous experiments had produced no definite evidence of pulsations, and the experiments would be repeated ...
