Observations of the Characteristics of Propagation of VLF Signals during Meridian Transits by SCO X-1,

Abstract

We have conducted a series of studies of the VLF propagation characteristics during coordinated radio, optical, ultraviolet, and X-ray observations of the X-ray star Sco X-1. The observations were taken from 9-12 March 1989, a period when Sco X-1 was particularly active, and during a time of intense day-side solar activity. VLF sites were used to obtain phase and amplitude data from the VLF transmitter and from more remote transmitters. This paper gives preliminary results which compare the time-varying X-ray flux with the VLF phase data taken during the observation.
