Abstract
β1 Monocerotis is a Be star with a V/R cycle of 12.5 years. We observed the star from CTIO (Chile) and with the IUE satellite and found that the star undergoes photospheric oscillations of 1.7 hours and presents a chromospheric structure in the extended atmosphere. Infall velocities and ejection of material are discussed.
