Abstract
Photoelectric and spectrographic observations of the Be star λ Eri made during five nights indicate that the luminosity variations have a different periodicity from that of radial velocity variations. This result seems to show that, at least during our observing time, the observed variability has not to be ascribed to a pulsation of the star.
