Subject: Re: [SkywavesDX] Solar Eruptions

 

 
Three years ago I spent about four months with a spreadsheet, using a formula 
devised by a NASA contractor that showed how the magnetic fields of the planets 
affect the solar flux and sunspot cycles. I elaborated on what he had published 
and came up with a chart that reasonably reconstructed the measured sunspot 
activity back to the 17th century, and which showed that this cycle and the 
next three are going to be very low:

Unlike other predictions from NASA, ARRL, and others, I have not modified this 
prediction since I completed the spreadsheet some three years ago. I do update 
the chart by adding measured monthly average sun spots counts as they become 
available at the beginning of each month from the Royal Observatory of Belgium
