Abstract

THE study of variable X-ray sources is severely handicapped by the short duration of a single rocket or balloon flight. The advantages of a method of monitoring celestial X-ray fluxes from the ground for prolonged periods are obvious. Two techniques suggest themselves: (1) observation of fluorescent optical and infrared radiation to which the atmosphere is transparent; (2) radiowave observations of those ionospheric parameters (for example, electrical conductivity) known to be affected by X-radiation.
