J/A+A/422/337       Solar EUV Post-Eruptive Arcades            (Tripathi+, 2004)

The Basic Characteristics of EUV Post-Eruptive Arcades and Their Role as Tracers of Coronal Mass Ejection Source Regions. Tripathi D., Bothmer V., Cremades H. <Astron. Astrophys. 422, 337 (2004)> =2004A&A...422..337T
ADC_Keywords: Sun ; Photometry, ultraviolet Mission_Name: SOHO Keywords: Sun: corona - Sun: coronal mass ejections (CMEs) - Sun: flares - Sun: filaments - Sun: photosphere - Sun: solar-terrestrial relations Abstract: The Extreme ultraviolet Imaging Telescope (EIT) on board the Solar and Heliospheric Observatory (SOHO) spacecraft provides unique observations of dynamic processes in the low corona. The EIT 195Å data taken from 1997 to the end of 2002 were investigated to study the basic physical properties of post-eruptive arcades (PEAs) and their relationship with coronal mass ejections (CMEs) as detected by SOHO/LASCO (Large Angle Spectrometric Coronagraph). Over the investigated time period, 236 PEA events have been identified in total. For each PEA, its EUV lifetime as derived from the emission time at 195Å, its heliographic position and length, and its corresponding photospheric source region inferred from SOHO/MDI (Michelson Doppler Imager) data has been studied, as well as the variation of these parameters over the investigated phase of solar cycle 23.
