We analyze multi-spacecraft observations of a giant filament eruption that occurred during 26 and 27 September 2009. The filament eruption was associated with a relatively slow cor…
A Technique for Removing Background Features in SECCHI--EUVI He II 304 A Filtergrams: Application to the Filament Eruption of 22 May 2008
Guy Artzner, Sanjay Gosain, Brigitte Schmieder
The STEREO mission has been providing stereoscopic view of filament eruptions in EUV. The clearest view during a filament eruption is seen in He II 304 A observations. One of the m…
