Observations of an Increase in the Flux from Tau A during Occultation by the Solar Corona

Ii: mid-June each year the aolar corona occults the radio source Tau A. These occ-.ltationa yield val^;able data concerning the radio transmission properties of the ccrora (Hewish, 1955; Erickson, 1964) . At wavelengths above 2 m, the observations appear to be reasonably consistent with the multiple scattering mechaniLm, proposed by Hewish, and the scatter ir-g appeare to e gale pruportiorrally to h?-Blum and Boisehot (191 )7, 1 1)')9) , using the Na:;cey sc,lar interferometer, have reported
