Indicated in the Berillium-10 measurements
That something big happened in this timeframe is indicated in the Berillium-10 measurements. Note that a deep down-spike occurred during the valley between the highest sunspot cycle of the 1960s, and the one before. The blue down-spike represents a corresponding up-spike in solar cosmic-ray flux.
