Scientific paper

The 93-cm Manuel Foster Observatory telescope in Chile has been used to obtain 919 spectrograms of 85 southern Be III-V stars. Balmer emission-lines (mainly H-beta) were noted in 74 percent of the stars, and Fe-II emission in 48 percent of them. Variations noted include rapid V/R variations of HR 1956, a primary shell phase of HR 2142, a shell phase of HR 2356, a transitory emission state of HR 2745, and the disappearance of the H-beta emission of HR 5193.
