| Abstract: | The low-frequency radio spectrum of the continuum emission from the undisturbed Sun is determined for 24 days during the period
1985 May-September. It is found that the spectral index varied from + 1.6 to +3.6 during this period. It is suggested that
the large positive spectral indices are due to the existence of temperature gradients in the outer corona. |
