A model for explaining the generation of the solar magnetic field and the related observational features (mainly solar cycle, Sporer's law, Hale's law, Joy's law, polarity reversal). The global frame
of this model is the interaction between a turbulent plasma in the convective zone (reciprocal generation of magnetic and electric fields) and the solar differential rotation (mutual transformation of meridional magnetic field into azimuthal magnetic field).

An eclipse in which the Earth passes through the shadow cast by the Moon. Solar eclipses only happen when the Moon is new and when the Moon lies close to the node of its orbit.
A part of the solar corona defined by the emission lines of hot gases. These emission lines include the so-called forbidden lines of the strongly ionized atoms of iron, calcium, and other elements. Th
e E corona is thinner than the K corona and the F corona.
A solar energetic particle event is a sudden release of particles (protons, electrons and heavy ions) with energy ranging from a few tens of keV to GeV and associated with solar eruptive phenomena or
interplanetary coronal mass ejections.
During an eruptive event on the sun, the sun can emit very fast, very energetic particles that travel at about 80% the speed of light. Such charged particles can reach Earth's magnetosphere either in
the wake of a flare, or propelled ahead of a coronal mass ejection. In either case the energy they dump into the atmosphere can create what's called a solar radiation storm, which can cause low frequency radio blackouts at Earth.
