Far UV Spectra of Fast Coronal Mass Ejections Associated with X-class Flares
J. C. Raymond, A. Ciaravella, D. Dobrzycka +4
The Ultraviolet Coronagraph Spectrometer (UVCS) aboard the {\it SOHO} satellite has observed very fast Coronal Mass Ejections (CMEs) associated with X-class flares. These events sh…
