| Abstract | A brief summary of observational data is presented, covering the disturbances recorded within seconds of high-altitude nuclear explosions, with particular emphasis on the "phase B" signal recorded at H
+ 2 seconds following the "Starfish" test of July 9th, 1962. The salient characteristics of this signal are specified: global synchronism at 2 seconds after the explosion ( ± 0.1 - 0.2 secs), large initial amplitudes (up to 30 - 50 Y) with an
extremely sharp rise, initial frequency 0.25 - 0.28 cps, and altitude dependence, occurring only if the source is above the E layer. Ten possible mechanisms are discussed and tested against the observational data. It is concluded that the only
mechanisms which would satisfy all the observed characteristics are those involving hydromagnetic-electromagnetic conversions. Although no conclusive decision can be reached on the basis of presently available data, the most likely one of these
mechanisms appears to be hydromagnetic waves along the field line through the detonation point, with energy conversion into electromagnetic modes at the mirror points. |
