Abstract. A mid­latitude filament was observed before and af­
ter its eruption with SOHO (EIT, SUMER, CDS and LASCO)
and with ground based observatories (Meudon and Pic du Midi)
in the context of a coordinated MEDOC campaign in Orsay. The
eruption was followed by a large Coronal Mass Ejection well ob­
served by LASCO. Few hours before its eruption, the filament
