Contemporary History,d changes in the magnetic flux. Global helioseismology yields information about solar structure in general while local helioseismology bears on three-dimensional structure and dynamics. Processes which underpin secular solar history, such as the creation of cosmogenic isotopes, are also clarified by the new data.

Origins,uminium-rich inclusions or CAIs) which are thought to have originated in the solar nebula, and the implications of the Standard Solar Model (SSM), for which helioseismology now provides corroboration. The generally accepted result is ~4.57 Gyr. The protoSun joined the Main Sequence, as depicted on H

Isotopes and Ice Cores, (.Be) has a half life (t.) of 1.5 Myr. Its short atmospheric residence time means that changes in .Be production can be traced at high resolution in stratified ice, but extracting the solar signal is complicated by climatic, geomagnetic and other factors and is performed confidently only for data f

Cosmogenic Radiocarbon,ry is obscured by climatic and biological factors, but comparison with the .Be signal is helpful where the evidence is derived from ice cores; elsewhere the .C data can be supplemented by information on changing climatic zonation using cave and river deposits.

The Solar Cycle,he dipole component of the Sun’s magnetism as a whole. The cycle is manifested in satellite records of total and variable solar luminosity, in the open solar magnetic flux, which can be estimated from solar observation or from the aa geomagnetic index, and in the Sun’s radio emission The incidence o

Solar Rotation,model of sunspot generation, first proposed in 1961, but the mechanism remains qualitative. Cogent explanations for the latitude effect had to await the advances in computing of the twentieth century but the resulting models were eventually invalidated by the findings of helioseismology.

Lessons from History, the lunar regolith and meteorites exposed to cosmic rays at different times. However the fossil neutrino evidence, especially from tellurides, may eventually provide successive snapshots of the solar interior. Cyclical and aperiodic changes in TSI and UV are well documented for recent millennia, al
