Spacecraft problems in association with episodes of intense solar activity and related terrestrial phenomena during March 1991

An intense period of solar activity in March 1991 initiated a sequence of major terrestrial effects including the generation of a second inner radiation belt, satellite anomalies, and power surges on electrical power grids. The solar-terrestrial phenomena associated with these various effects are identified and placed in context with similar disturbances this solar cycle. The various spacecraft and ground-based anomalies which occurred are associated with the geophysical environment at the time of the occurrence
