Abstract

(Abstract only) The Be stars are a group of bright B-type stars with emission lines in their spectra. They vary in brightness, by up to a few tenths of a magnitude and on time scales of hours up to years. The nature and cause of this variability are not fully understood. For these reasons, an international professional-amateur photometric campaign has recently been organized by Drs. P. Harmanec, J. Horn, and P. Koubsky of the Ondrejov Observatory of the Czechsolovak Academy of Sciences.
