Abstract
THE recent discovery of bursts of γ rays of cosmic origin1 has led to the suggestion that these bursts might produce observable ionospheric effects. Since γ rays are absorbed at a relatively low altitude when compared with most other types of ionising radiation, the thought was that these bursts would produce additional ionisation which might be strong enough to affect v.l.f. radio propagation data. If so and if data from several paths were obtained, it might be possible to obtain information about the location of the sources. Directional information from the Vela satellites, when obtained at all, contains an inherent ambiguity.
