Erupting flux rope, rising x-ray source and a slow CME on 16 april 2002
A long-duration event (LDE) linked to a slow coronal mass ejection (CME) was observed at the NW solar limb on 16 April 2002. A multiwavelength analysis involving TRACE, RHESSI, SOHO/EIT, CDS and LASCO observations as well as magnetic modelling (SOHO/MDI) provided several new pieces of evidence suppo...

A multiwavelength analysis involving TRACE, RHESSI, SOHO/EIT, CDS and LASCO observations as well as magnetic modelling (SOHO/MDI) provided several new pieces of evidence supporting the classical LDE/CME scenario: the event started with the eruption of a filament, which was found to have helical mass motions when crossing the CDS spectrograph slit situated 50" above the limb.

We also found down-flows of plasma in hot, newly reconnected flare loops and an exponential acceleration of the erupting filament between the TRACE and LASCO/C2 fields of view.

A long-duration event (LDE) linked to a slow coronal mass ejection (CME) was observed at the NW solar limb on 16 April 2002.
