Electron density profiles in the night-time auroral ionosphere were obtained with the incoherent-scatter radar at Chatanika, Alaska, during short duration precipitation events characterized by riometer data as spike events. The measurements show exceptionally large electron densities in the D-region during spike events, the electron density exceeding one million cu cm at 90 km altitude for a short time. It is shown that 20-40 keV electrons make the greatest contribution to an absorption spike and that the spectrum of electrons producing it is probably softer than that resulting in more slowly varying absorption peak; these absorption layers are too high to be measured by the technique of multifrequency riometry.
