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

🌟 Final update on the flare. Peak GOES-18 0.1-0.8 nm X-ray flux was X1.21 on 10.11.2025 at 09:19:00 UTC

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.

And... Another X-class solar 💥flare💥 !
Today, Nov 10, peaking at 09:18UT an X1.2 flare was detected.
Here is the Hα light curve also showing the GOES X-ray light curve

Verbrennerverbot? Nein! Doch... 🚗 Auf dem Ecosystem Summit der Schwarz-Gruppe in Berlin hat er sich am Freitag klar positioniert: "Es ist grundsätzlich falsch, wenn der Staat einseitig Technologien vorgibt."
