The latest thing I’ve cobbled together with n8n is a routine that goes out to https://sol24.net/ and pulls in the current Aurora forecast and the current 7 day video of solar flares into my dashboard. I’ve always had a fascination with how the sun affects the earth and the protective layers of our atmosphere, since I was a child. I built my own 5 watt, code only, transmitter and receiver and would set in my room late nights collecting QSL cards and talking to people from all over the world . I quickly learned that the ionosphere and other protective layers affected how far my little 5 watt signal would bounce. Solar flares burn holes in the ionosphere and prevent a good bounce halfway around the world. So the challenge was to pick days where there was good ionosphere coverage, and minimal solar flares in conjunction with antenna positioning.

This is the current video which takes you from 11/29 to 12/5. It’s mind boggling to me the absolute power and energy represented: https://sol24.net/data/stereo_7day_euvi304.mp4

You could probably conjure up something in bash to do this, but I really like working in n8n.
