We will first give a definition of what is a prominence according to the glossary of Solar Physicists. A prominence is a filament observed at the limb. A filament lies over the inversion line of photospheric longitudinal magnetic field and is supported in dips of horizontal magnetic field lines. Recent models of flux tubes prove that fine structures of prominences could be represented by vertical structures embedded in dips of horizontal field lines.
Observations of a prominence observed in H? by Hinode/SOT and the solar tower of Meudon show a very high dynamic nature. SUMER spectra in Lyman series show no reverse profiles indicating a large prominence corona transition region.
This prominence is surrounded by a large coronal cavity as show spatial telescopes (TRACE, XRT).
These results will be discussed in term of different formation models.
