Anatomy of a Flare and Coronal Mass Ejection
Abstract
In this paper we present the observations of a flare, CME and their interaction obtained with the SOHO, Trace, and Yohkoh spacecraft. More specifically we show evidence for wave-like motions in the Trace 171 observations, of comparable speed to those usually inferred from EIT observations and thus termed `EIT waves'. We find that these waves commence at the same time at which a prominence is observed to rise within the active region and signifies the start of a gradual coronal mass ejection. The prominence is observed with the Coronal Diagnostic Spectrometer, on SOHO, with red and blueshifts which can only be reconciled if the structure is rotating close to the plane of the image with an angle of ~ 72o, to line of sight. During, the impulsive phase of the flare the prominence and CME is observed to accelerate from 190km/s to 900km/s.
