摘要: Abstract In a few cases of very strong absorption long duration observed at Kiruna Geophysical Observatory during the summer 1958, height upper boundary ionized layer has been found to be about 50 km. It is shown that this value accords well with what expected if ionizing agent consists protons. Earlier proposed interpretation discussed regard new information.
