Abstract : This grant was used to support the Ms and post-MS studies of Tom Spirock and Elliotte Harold. Mr. Harold studied data on acoustic event on the the Sun. From this, we learned that sunquakes, which enable us to seismically probe the inside of the Sun, have an unexpected source. We discovered that the quakes are caused by a catastrophic cooling and collapse of isolated, small regions of the Sun's surface. It had been widely believed that these quakes were caused by the steady drumming of material rising to the solar surface. Mr. Spirock developed a robotic, computer controlled arm for his thesis. This work represented a significant expertise in building instruments and using computers to control them.
