Observations by a 7x7-beam imaging riometer in Kilpisjärvi, Finland (~66° MLAT) of the drifting cosmic noise absorption (CNA) structures in the morning sector near the zonal drift reversals are presented. The examination of the absorption intensity images revealed several regions with enhanced CNA (...
