  Solar magnetic fields evolve on many time-scales, e.g., the generation,
migration, and dissipation of magnetic flux during the 22-year magnetic cycle
of the Sun. Active regions develop and decay over periods of weeks. The
build-up of magnetic shear in active regions can occur within less than a day.
At the shortest time-scales, the magnetic field topology can change rapidly
within a few minutes as the result of eruptive events such as flares, filament
eruptions, and coronal mass ejections. The unique daytime seeing
characteristics at Dome C, i.e., continuous periods of very good to excellent
seeing during almost the entire Antarctic summer, allow us to address many of
the top science cases related to the evolution of solar magnetic fields. We
introduce the Advanced Solar Photometric Imager and Radiation Experiment and
present the science cases for synoptic solar observations at Dome C.
Furthermore, common science cases concerning the solar-stellar connection are
discussed in the context of the proposed International Concordia Explorer
Telescope.
