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...
