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.
=A0
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.
=A0
It would be nice to monitor the EUV levels from the Sun as well...
=A0so my question is really "does anyon= e know of a source of Internet data for this radiation?"


Hello Hugh,

perhaps, the link below =A0 could=A0 be of some interest to you
