The Ritter Observatory classical Be star observational  program

        Spring 2002 (version 4)
Aim

Long-term monitoring of the spectral lines' behavior in order to study physics of circumstellar matter around Be stars in more detail, reveal their nature,  and variation mechanisms. This program will be supported by optical observations by collaborators in Kazakhstan  (since September 2001).
