Abstract
The solar Lyα line emission can be considered as the dominant source of
ionization processes in the ionospheric D-region at altitudes above 70 km
during unperturbed conditions. However, large sudden impacts of radiation in
some other energy domains can also significantly influence the ionization
rate and, in this paper, we present a study on the contribution of Lyα
radiation to the ionization rate when the ionosphere is disturbed by solar
X-flares. We give relevant analytical expressions and make calculations and
numerical simulations for the low ionosphere using data collected by the VLF
receiver located in Serbia for the VLF radio signal emitted by the DHO
transmitter in Germany. [Projekat Ministarstva nauke Republike Srbije, br.

期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
