Solar-interplanetary circumstances associated with the major events in March and June 1991 and comparison with similar events of previous solar cycles
Technical Report
·
OSTI ID:381604
The solar activity and geomagnetic storm events of March and June 1991 were associated with the appearance of an enhanced particle flux in the trapped radiation belts as discovered by the CRRES satellite observations and later measured by shuttle radiation detectors. The solar interplanetary conditions associated with these events appear to be a major sequence of activity near the sun`s central meridian generating powerful fast interplanetary shocks resulting in major perturbations to the magnetosphere. The solar interplanetary events in 1991 are discussed and compared to similiar activity in the past such as the events in February 1986, August 1972, July 1961, November 1960, and July 1959.
