A solar energetic particle event observed on July 9, 1996 with the COSTEP-EPHIN experiment onboard the SOHO spacecraft in the Lagrangian point L1 of the Sun-Earth system. The upper panel shows an image of the Sun taken on the same day with the SOHO-EIT in Fe XV (28.4 nm). The bottom panel shows intensities of 0.25-0.7 MeV electron, 4.3-7.8 MeV protons and 4.3-7.8 MeV/n helium nuclei measured with COSTEP-EPHIN. The intensity increases of the energetic particles at SOHO were caused by a flare and coronal mass ejection in an active region in the Sun's western hemisphere .
