The Delta Scuti Network (DSN)

The Delta Scuti Network (DSN) is a collaboration of astronomers from all around the globe who observe and study short period variable stars. It was founded by Michel Breger at the University of Texas (McDonald Observatory) and at the University of Vienna (Institute of Astronomy) in 1983 with the goal to improve the frequency solutions of multiperiodic Delta Scuti stars.
