Bosse And Vahrenholt: Solar Cycle 24 Observations


German scientist Frank Bosse and Fritz Vahrenholt, on 12 March,  bluesunUnknownprovided another way to look at Solar Cycle 24. It is worth sharing. They posted “The Sun In March 2015” on the Notrickszone.com website. They begin by saying:

“Last month our sun gave a really sluggish impression. The sunspot number (SSN) was only 38.4: only 46% of what is normal at this time into a cycle for all the cycles observed since 1750.

The following chart illustrates their assertion:

(March was the 76th month since the start of Cycle 24. These numbers will change as the Cycle 24 progresses, but the low activity will likely to continue to result in under performing almost all of the previous Cycles. )
