  • Abstract: The energetic solar particle event on November 6, 1997 produced the highest particle intensities above MeV/nucleon since the launch of the Solar and Heliospheric Observatory (SOHO) spacecraft in December 1995. There was a X-ray flare associated with a coronal mass ejection (CME) which had an exceptionally high leading edge velocity (1560 km/s) as observed by the Large Angle and Spectrometric Coronagraph (LASCO) on board SOHO. The Energetic and Relativistic Nucleon and Electron experiment (ERNE), also on board SOHO, measured high He, O, and Fe fluxes in energy channels from 4 to 80 MeV/nucleon. The ERNE observations might indicate that there were two energetic particle sources operative in solar atmosphere and/or interplanetary space during several hours after the solar flare eruption.
