                         23. Since 1996, the post-SOHO era, we had a number of 18 
                         Dst<-200nT events, which where observed continuously, both near 
                         the sun and in the near-earth interplanetary space. We use data 
                         from the Large Angle and Spectrometric Coronagraph and the Extreme 
                         Ultraviolet Imaging Telescope, both aboard the Solar and 
                         Heliospheric Observatory, to identify the solar origin of these 
                         events. Solar wind and interplanetary magnetic field from the 
                         Advanced Composition Explorer are used to study these events in 
                         terms of their interplanetary structure. In terms of solar sources 
                         of these extreme events, all but one were associated with coronal 
                         mass ejections alone, while one event was related to a coronal 
                         hole high speed stream interacting with a slow CME.",
