Resumen:
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 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.
Rising with the filament, a coronal X-ray
source was identified as a plasmoid originating
from the interaction between upward
reconnection outflow and the closed magnetic
structure of the erupting filament. 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.
