Magnetic Effects Resulting from Two High-Altitude Nuclear Explosions

Article metrics

Abstract

ON August 1 and 12, 1958, two nuclear devices were exploded in the upper atmosphere above Johnston Island in the North Pacific. No exact information is available to us regarding the heights of the explosions ; but it is believed that the first explosion was higher than the second. Unusual magnetic effects, mentioned previously by Cullington1, were recorded after both explosions on magnetographs at Honolulu, Palmyra Island, Fanning Island, Jarvis Island and Apia. Fig. 1 shows the location of these observatories.
