The Ritter Observatory classical Be star observational  program

                  Summer and Fall 2001
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 and near-IR photometric observations by A. Miroshnichenko in Kazakhstan (July-August 2001).
