ResumoSolar X-ray and extreme ultraviolet (EUV) photons are responsible for ionizing the terrestrial atmosphere and create the ionosphere. During solar flares, a fast increase in the electron density at various altitude regions takes place due to the abrupt enhance of the X-ray and EUV fluxes toward Earth. With these changes in the ionosphere, radio communication and navigation can be drastically affected. The magnitudes of these kind of Space Weather events can be related to the X-ray peak brightness and the duration, which drive the intensity of the ionosphere response when the associated electromagnetic wave hit the sunlit side of the Earth atmosphere. Other aspects defining the severity of damages to HF radio communications and LF navigation signals in a certain area are the local time, the solar zenith angle, and the position of the flare in the solar disc. In order to improve the understanding of radio signal loss or degradation in the Brazilian sector due to solar X-ray emissions, we analyze total electron content (TEC) maps and curves at selected sites obtained by a GPS network formed by tents of dual-frequency receivers spread all over Brazilian territory. We observe different ionospheric local changes during several X-ray events in the 0.1-0.8 nm range identified by GOES satellite. Considering the results, we have made an estimation of the severity and range of ionospheric disturbances in the equatorial and low-latitude Brazilian region affecting space based communication for different events based on their characteristics.
