Geophysical Effects of High-Altitude Nuclear Explosions
Geophysical effects of nuclear tests carried out in Augast 1958 at Johnston Island in the Pacific are discussed. These tests were reported to include highaltitude explosions at heights of the order of 100 miles. Observations show that one test coincided with the appearance of an aurora and the occurrence of radio fade-outs at Apia, which lies at the opposite end of a geomagnetic line of force. Variations in time of signals received, atmospheric noises and mean diurnal variation of atmospheric noise are plotted. Observed effects are discussed and are compared to those accompanying the sudden ionospheric disturbance due to solar flare.
