Solar and Geophysical Associations with the Principal Energetic Particle Events in 1971 and 1972,
Abstract
For 1971 and 1972, 202 distinct, energetic particle enhancements have been identified. Solar and geomagnetic circumstances prior to each of these proton increases have been evaluated. For 93 of the particle enhancements, confident flare or geomagnetic associations could be established. These events included 27 relatively high energy (19-80 or > 60 MEV or PCA) proton enhancements. An additional 17 high energy increases were observed, but assured solar or geomagnetic associations could not be established. Tabulations have been prepared of solar and geomagnetic circumstances prior to all events with assured flare or geomagnetic associations and/or high energy proton detection. The tabulations of this report provide solar and geomagnetic data for approximately 50% of the identified energetic particle events in 1971 and 1972. The remaining events included only those with lower particle energies and the less confident solar or geophysical associations. (Author)
