Abstract
The analysis of type III bursts observed from the OGO-5 satellite between 3.5 MHz and 50 kHz (λ6 km) gives an empirical expression for the frequency drift rate as a function of frequency that is valid from 75 kHz to 550 MHz. Using this expression and some simplifying assumptions we obtain indirectly an empirical formula for the electron density distribution of the solar wind to 1 AU which is consistent with published values of electron density and with observed type III burst drift rates.
Also J. Fainberg, L. G. Evans, and R. G. Stone have recently reported the detection of bursts at 30 kHz. (Science 178 (1972), 743.)
