Hello group,
I was re-reading the chapter on propagation in an RSGB book on Operating Practice, and it said that the ionisation of our precious F layers (and also the D absorbtion layer) was caused by Extreme UV radiation. This is wavelengths 120nm up to 10nm.
 
We monitor the solar wind and solar flares to try and predict what changes in propagation will occur, but these things seem mainly to be negative influences on propagation - things which disrupt the propagation.
 
It would be nice to monitor the EUV levels from the Sun as well...
 so my question is really "does anyone know of a source of Internet data for this radiation?"



Hello Hugh,

perhaps, the link below   could  be of some interest to you
