Therefore, to understand and predict "space weather" and the effect of solar activity on the Earth, an understanding of both CMEs and flares is required.

Solar flare - Wikipedia

WebOne of the methods of detection and analysis of solar flares is observing the time variations of certain solar spectral lines. During solar flares, a raise of electron concentration occurs in Earth's ionosphere which results in amplitude and phase variations of the recorded very low frequency (VLF) waves. We compared the data obtained by the analysis of recorded VLF … WebThe ionosphere is a dynamic part of the upper atmosphere which acts as a reflector for long range, high frequency communications (HF comms). During a solar flare the increase in x-ray radiation from the Sun causes the ionosphere to absorb rather than reflect signals and this disrupts communications systems on the sun-lit side of the Earth. portable propane room heaters
