Abstract : A good correlation for the events studied has been found between the absorption of cosmic noise and the luminosity of the aurora overhead. This supports the view that the excitation of aurora and the absorption of radio waves are caused by the same energy source. There appears to be a time delay between outbursts of auroras and the increase of absorption. This time delay has been found to be a few minutes in good agreement with current information of upper atmosphere parameters. Correlation between the magnetic X-component and the auroral intensity was good except for the events when the aurora was spread out over great parts of the sky. (Author)
