Abstract : OBLIQUE AURORAL ECHOES AT 92.8 Mc from the Kemi FM-transmitter station, situated 310 km south-southeast of Kiruna, were investigated at Kiruna Geophysical Observatory for more than two years of continuous recordings (October, 1957 to May, 1960). The results of the investigation of VHF aurorally propagated transmission with regard to diurnal, day-to-day and seasonal variation, as well as the duration and the signal strength of the echoes are reported. The correlation with solar and magnetic disturbances has also been studied. (Author)
