Introduction
A major new discovery about solar flares appeared as recently as 1997, when a set of concentric, expanding ripples appeared on the solar surface immediately following the flare SOL1996-07-09 (see earlier Nuggets No. 26 and No. 127). These phenomena hold great interest because they come from acoustic waves launched by the flare that surprisingly penetrate into the Sun's deep interior, and that contain substantial fractions of the flare's total energy. At present no broadly accepted theory exists.
