During November 1960, a number of outstanding disturbances of the earth's upper atmosphere occurred which have been attributed to the arrival of energetic, charged particles from major flares on the sun. These disturbances have been studied with the aid of a number of riometers at stations located along a north-south line across the auroral zone- from Resolute Bay to Ottawa, Canada. Ionospheric absorption data are presented for the period 12-17 November with particular emphasis being placed on the polar cap absorption events of November 12 and November 15. The ratio of absorption at 30 Mc/s to absorption at 60 Mc/s has been evaluated for certain periods. These data are discussed and interpreted in terms of height of the absorbing region. (auth)
