Abstract
Discussion about sources of energetic particles - solar cosmic rays (SCRs), or solar energetic particles (SEPs) - emerging in the interplanetary space after an explosive energy release on the Sun lasts during more than 20 years. The main candidates for the SEP sources are a solar flare and a coronal mass ejection (CME). This paper briefly outlines the main observational results related to the problem of the SEP origin. Main focus is directed to the recently discovered manifestations of the sudden energy release on the Sun - long lasting high-energy solar gamma emission, new information on solar neutrons and THz radio emission. Actually, description of particle acceleration on the Sun appears to be even more complicated than it was believed earlier.
