Lyman-Alpha data can provide early (precursor) detection on the disk, hours before filament/prominence eruptions.In order to have a good understanding of the pre-eruption conditions we need to identify the conditions for each case of eruption. We have thus created a list of filament eruptions and performed the allowing statistical study for it. This Filament\ Prominence eruption list divides in to confined and ejective eruptions. We use the solar dynamic observation SDO with AIA instrument 171 Ao) to determine the twist angle of the filament eruption for selecting confined or ejective filament ER -
