The Ionosphere

Being an engineer, a pseudo-physicist and also a radio ham, the ionosphere is of considerable interest to me. So, below I post some news on the interplay between sun and planet earth.

Earth magnetic field variation over time. Solar wind affects occasionally the normal curve pattern. At the end of the 8th day of July, we had a big hit by solar wind = solar particles. The earth magnetic field time curve reflects the impact we just experienced.
