Well it is January 2017, and I have read that there have been 35 spotless days in a row. That's more then the June-July streak. Could it be that sunspot minimum could be reached within the next year, instead of 2019-2020, as shown in http://www.swpc.noaa.gov/products/solar-cycle-progression. Wouldn't that be the beginning of solar cycle 25. This would mean a solar sunspot cycle length of 9 years, which would be in the range of 7-15 years for a sunspot cycle, so it doesn't seem that would be unusual. What do you think ?

The spotliess activity is happening sooner than they predicted. There is talk that we are headed into a grand solar minimum with cycle 25 predicted to only max out at 50 sunspots at it's peak. Should be interesting to see if it has any affect on climate or if AWG counteracts it somewhat. Link to comment Share on other sites More sharing options...
