Before a #CME hits Earth's magnetic field, high-speed solar wind streams and energetic particles can already reach Earth. These interact with the ionosphere, particularly the F2 layer. This interaction can temporarily increase ionization in the upper ionosphere #hamradio #spacewx

Here is the latest SWPC graphic regarding the recent X1.2 flare from AR 4274. Again, X-flares are not unusual around solar maximum, and Earth-directed CMEs of this caliber are not "dangerous." This is not a Carrington-class event by ANY means.

If you think the Ionosphere is bad now, wait until the CME from this flare hits Earth in a few days...
