[RVRC] The Maunder Minimum and Climate Change: Have Historical Records Aided Current Research

[HMLong]

Hello Hamsters,

I came across "The Maunder Minimum and Climate Change: Have Historical Records Aided Current Research?" It is located at this link at http://www.stsci.edu/stsci/meetings/lisa3/beckmanj.html

Paragraph 1. Introduction: the Solar Cycle and its Variation appears to have a non sequitur from the former first 2 sentences about sun spots. [ During sunspot maximum high-energy protons and alpha particles from the Sun affect the ionosphere, reducing its affectivity as a mirror from which short radio waves are reflected round the world, disrupting transmissions for days at a time. ] 

In general sun spots with their surrounding plages emit radio...uv... through x-radiation and alpha particles but the ...uv... spectrum generally and more often increases the ionization of the F2 layer which dominates over the less often emitted destructive alpha particles to the F2 layer which is a less common event even at solar maximum. Yes? No? Am I incorrect here or should this be corrected to give better understanding to the effect of sun spots to HF propagation in that paragraph even though it is not central to the subject? 

What is your understanding about this?

Happy 4th
