10. Kahler et al. (late 1970s and early 1980s) found strong correlation with CMEs Cane et al. (1986) made association with 2 types of radio bursts Solar Energetic Particles (SEPs) only flares Old picture - up to 1990s’ Current picture - two classes First discovered - Forbush 1946 from ground based ion counters Closely related to H  flares - (Meyer 1956)

11. Where? At CME-shocks or in flares Source material? Ambient corona, solar wind, or other Mechanisms? Reconnection or CME- shock acceleration Transport to Earth? Scattering, Turbulence, fluctuations SEPs: Big Questions
