THE ROLE OF FLARES, CMES AND CME SHOCKS IN THE GENERATION OF SOLAR ENERGETIC PROTON EVENTS

We examined solar energetic proton (SEP) events associated with intens e Ha flares. We located: these flares on the solar disk and obtained t heir distribution in heliographic longitude as well as their angular d istance distribution with respect to the neutral lines corresponding t o the heliospheric current sheet at 2.5 R(circle dot). We found that t he SEP-associated Hct: flares tend to occur in active regions at the f eet of those helmet streamers which form the heliomagnetic equator and are related to coronal mass ejections (CMEs) and CME shocks. We discu ss the possible role of flares, CMEs and CME shocks in generating SEPs .
