No argument that sunspot activity increases solar radiation. However, solar radiation, reduces the amount of cosmic radiation that reaches the earth. Increased sunspot activity means less cosmic radiation, which is what we were talking about.
WW,
Great discussion! As I am now into drink #2 of a fine 7 year aged single batch bourbon I will not attempt to challenge your science. However, I will refer you to the following link that tells you just about everything you need to know about inflight radiation, cosmic, galactic, solar etc!
And for those not bored by this discussion yet, the AC I referred to earlier is AC 120-61A.
Cheers,
AKG
