At 1000 UT on October 26, 1962, a submagaton nuclear bomb was detonated at an altitude of tens of kilometers in the vicinity of Johnston Island. The burst produced phase perturbations of the stabilized 19.8-kc/s transmission from station NPM in Hawaii as received in Anchorage, Alaska, and the Applied Physics Laboratroy of the Johns Hopkins University. The VLF perturbations may be separated into: an instantaneous disturbance caused by charged particles immediately deflected from the burst region into the VLF transmission path; a delayed perturbation starting at 2 minutes after the burst with a peak at 4 minutes, and having a general temporal variation indicating that this phase variation is due to geomagnetically trapped BETA rays from the radioactivity decay of neutrons.
