Ive been fascinated by the solar research that is provided by Livingstone and Penn viz magnetic flux within sun spots declining and that decline seems to suggest a lessened bit of solar activity – to the point of extinction of sun spots by cycle 25. See the paper here.
Now there appears to be a second set of data that seems to corroborate the LP data with subsurface solar observations by Mr. Frank Hall. His data can be seen here.
Perhaps it is time to be thinking of the Low Bands and antenna considerations for same!
