Abstract
<jats:p>The paper presents the results of the analysis of nine simultaneous ground-based detection events of auroral hiss bursts at the Lovozero Observatory and cosmic radio noise absorption (riometric absorption) at the Lovozero and Tumanny observatories located on the Kola Peninsula. We have estimated the position of the area of increased absorption, using the results of riometric observations at these observatories and images from all-sky cameras in the Lovozero Observatory and nearby locations. The position of the area “illuminated” by auroral hisses was determined by measuring the azimuthal angle of the Poynting vector and the polarization of the magnetic field of the hisses. It has been found that for each event considered the area of illumination and the area of increased riometric absorption are located at different latitudes. This may explain the cases of simultaneous ground-based observations of the two phenomena in question, although auroral hisses usually disappear with a significant increase in riometric absorption.</jats:p>
