Night-time Anomalies in Very Low Frequency Propagation produced by a Galactic X-ray Source at Centaurus

Nature volume 228, pages 1080–1081 (1970)Cite this article

Abstract

NIGHT-TIME propagation of very low frequency (VLF) waves in the terrestrial ionosphere shows considerable variability, both in phase and in amplitude, in comparison with the relatively stable daytime conditions. The night-time anomalies are not yet well understood, a number of them being associated with the presence of energetic particles originating from solar proton events1. The explanation of others remains obscure.
