✦ Synopsis

A model is presented which shows that large numbers of energetic electrons (0.3-> 10 MeV) and protons (1-30 MeV) can be stored in the solar corona at altitudes around 3 • 105 km for periods in excess of 5 days. Specific reference is made to the time period July 6-16 1968 as an excellent example of energetic solar particle storage. Time histories of interplanetary charged particle intensities observed by the IMP-4 and Pioneer 8 satellites are used to substantiate this contention. Detailed reference is also made to solar X-ray, optical and radio data obtained during the period in question, in addition to interplanetary magnetometer data. This model provides a unique solution to many hitherto unexplained solar particle events, and can also account for the lack of prompt particle emission from certain large solar flares recorded in the past.
