Abstract

We report the observation of a Coronal Mass Ejection (CME) detected on June 27 1999 by the Ultraviolet Coronagraph Spectrometer (UVCS) telescope operating on board the SOHO spacecraft. The CME, whose leading edge was expanding at a projected speed of about 1200 km s^-1, was observed in white light by the Large Angle Spectroscopic Coronagraph (LASCO). The UVCS spectra reveal excess broadening of the O VI doublet lines and enhancement in the intensity of the Si XII lines due to the motion of expanding hot material. The evolution of the UVCS structure is highly correlated to the evolution of the CME observed by LASCO in white light, so that the hot gas emission could be attributable to the passage of a shock wave propagating just in front of the fast CME.
