Description
The prediction of space weather is an important goal in solar physics,
and has consequences for aviation, satellite technology, manned space flight, and power grids on Earth. Helioseismology provides a way
of looking underneath the surface of the Sun using naturally
occurring sound and surface gravity waves.
After introducing some basics of Helioseismology, I will discuss the
possibility of space weather prediction, based on the analysis of
three active regions (ARs), for which, the solar surface mode
(f-mode) displays strengthening already about two days prior to
AR formation. Its implications for global solar dynamo models will also
be discussed.
