Scientific paper

Well-developed filament channels may be present in solar atmosphere even when there is no trace of filament material inside it. When erupted, such “empty” filament channels could result in coronal mass ejections that might appear having no corresponding solar surface source region. We analyze the magnetic field configuration and eruption of a complete filament system, which includes magnetic neutral line, filament channel, and the coronal cavity, but without the filament material inside. We show that the presence of filament visible in H-alpha or He II 304 A is not necessary for the eruption of magnetic systems with "empty" filament channels.
