Enhancement Factor and True Absorption of the V.H.F. Cosmic Radio Noise associated with Solar Flares

Abstract

SOME abnormal absorptions of cosmic radio noise at the V.H.F. are closely associated with solar flares and can be measured by means of riometers. If there is no enhancement of radio noise emission, the absorption of cosmic radio noise can be simply measured by comparison with a quiet day curve, but enhancement of radio noise at the V.H.F. frequently accompanies solar flares. The absorption measured by comparison with a quiet day curve would be quite different from the true absorption, and the enhancement of radio noise should be fully taken into account for the measurement of absorption.
