SOLAR-INTERPLANETARY PHENOMENA IN MARCH 1991 AND RELATED GEOPHYSICAL AND TECHNOLOGICAL CONSEQUENCES

A short period of intense solar activity in March 1991 initiated a seq uence of major perturbations to the interplanetary and terrestrial env ironment, The cosmic ray intensity underwent rapid and extreme modulat ions, and a third radiation belt was created. In addition these pertur bations resulted in a wake of disruption to a variety of technological systems designed to operate in a more benign spatial and geophysical environment. The various spacecraft and ground-based anomalies which o ccurred are associated with the geophysical environment at the time of the occurrence. Copyright (C) 1996 Published by Elsevier Science Ltd
