Abstract
A RECENT article by Edwards et al.1 suggested that observations of the phase delay suffered by VLF radio waves propagating over large distances in the Earth–ionosphere waveguide revealed the presence of ionization in the night-time lower ionosphere produced by X-rays from the strong X-ray source, Scorpius XR-1. and other weaker sources in the vicinity of the galactic centre. These observations were taken on the 20 kHz transmissions from WWVL, Boulder, recorded in New Zealand.
