We use 20 MeV proton intensities from the EPACT instrument on Wind and coronal mass ejections (CMEs) from Sthe LASCO coronagraph on SOHO observed during 1998-2002 to statistically determine three characteristic times ) Sof gradual solar energetic particle (SEP) events as functions of solar source longitude: (1) To, the time from assoo ciated CME launch to SEP onset at 1 AU, (2) TR, the rise time from SEP onset to the time when the SEP intensity is a q "( Dfactor of 2 below peak intensity, and… CONTINUE READING
