Solar Activity Cycle

Abstract

Work focussed on describing the solar activity cycle's clock as a torsional oscillator, and describing the origin of the 5 minute oscillations, which are used as a seismic probe. It has been discovered that the sun's rotation does not vary near the base of the convection zone but may vary deeper down. The full equations for the torsional oscillator have been developed and have been solved for certain situations. It has been shown that the 5 minute oscillations are driven by granular size explosive events. In observational work, the observing set-up has been designed to capture the whole solar disk. Data is now able to be collected in a production mode. Data reduction programs also are in full operation. The basic behavior of 5 minute oscillations has been clearly seen. A search is underway for the global organization of convection to determine if giant cells exist.
