Flux emergence event underneath a filament
Flux emergence phenomena are relevant at different temporal and spatial scales.We have studied a flux emergence region underneath a filament. This filament elevated itselfsmoothly, and the associated CME reached the Earth. In this study we investigate the size andthe amount of flux in the emergence...

| Sumario: | Flux emergence phenomena are relevant at different temporal and spatial scales.We have studied a flux emergence region underneath a filament. This filament elevated itselfsmoothly, and the associated CME reached the Earth. In this study we investigate the size andthe amount of flux in the emergence event. The flux emergence site appeared just beneath afilament. The emergence acquired a size of 24 Mm in half a day. The unsigned magnetic fluxdensity from LOS-magnetograms was around 1 kG at its maximum. The transverse field as wellas the filament eruption were also analysed. |
