Ionization effects from cosmic sources of x-rays in the lower atmosphere

摘要: Detectable ionization effects in the ionosphericD-region from individual, strong and steady x-ray sources such as Sco X-1 transient Cet X-2 have been reported by us many others previously based on field strength phase variations of VLF data. As a follow up to these investigations, we examined integrated known discovered UHURU, ANS, Ariel V SAS-3 satellites, order understand totality their effects. These are present paper for 0° +38° geographic latitudes corresponding midnight conditions different times year. Such compared, turn, with those responsible forD-region Lyman-alpha galactic cosmic radiations. The results presented profiles electron production rates function height. Our study leads conclusion that there should be detectable annual density which pronounced around May-August. Further, computations spectacular nova A0620-00 also included paper.
