Quiet sun sets new record for spotless days – Evidence of SC-25

Reblogged from Watts Up With That


As of November 1st, the current stretch of days without any observable sunspots in solar cycle 24 has reached a total of 228 spotless days in 2019 so far That’s 75% of the year so far. During the 2008 solar minimum, there were 268 days without sunspots, or 73% of the year.

Here’s a tally of spotless days for the last solar cycle:

2019 total: 228 days (75%)
2018 total: 221 days (61%)
2017 total: 104 days (28%)
2016 total: 32 days (9%)
2015 total: 0 days (0%)
2014 total: 1 day (<1%)
2013 total: 0 days (0%)
2012 total: 0 days (0%)
2011 total: 2 days (<1%)
2010 total: 51 days (14%)
2009 total: 260 days (71%)
2008 total: 268 days (73%)
2007 total: 152 days (42%)
2006 total: 70 days (19%)

Meanwhile, a new cycle 25 sunspot was observed today. From Spaceweather.com :

Breaking a string of 28 spotless days, a new sunspot is emerging in the sun’s southern hemisphere–and it’s a member of the next solar cycle. A picture of the sunspot is inset in this magnetic map of the sun’s surface from NASA’s Solar Dynamics Observatory:

How do we know this sunspot belongs to the next solar cycle? Its magnetic polarity tells us so. Southern sunspots from old Solar Cycle 24 have a -/+ polarity. This sunspot is the opposite: +/-. According to Hale’s Law, sunspots switch polarities from one solar cycle to the next. Today’s emerging sunspot is therefore a member of Solar Cycle 25.

This development does not mean Solar Minimum is finished. On the contrary, low solar activity will probably continue for at least another year as Solar Cycle 24 decays and Solar Cycle 25 slowly sputters to life. If forecasters are correct, Solar Cycle 25 sunspots will eventually dominate the solar disk, bringing a new Solar Maximum as early as 2023.

Back in April 2019, an confab of solar scientists said:

Experts Predict a Long, Deep Solar Minimum

“We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak maximum, preceded by a long, deep minimum,” says panel co-chair Lisa Upton, a solar physicist with Space Systems Research Corp.

    So by Lisa Upton’s graphic it’s taken about 6years (from 2014) to get to the bottom of the solar minimum. How much longer will it take to ramp-up SC25? 5-6 years? Through most of that time the winters will be getting colder as most of the solar heat from the SC24 peak would have dissipated.
    In the short term (1-4 years) the winters will, in probability, get very cold and given the projected weak rise of the next solar cycle they are not likely to warm-up much (even at the peak of solar cycle 25). And after that (in about 8-15 years) it’s back to even colder winters as SC25 declines.

    No amount of mythical CO2 ‘warming’ will protect anyone from this. The growing season will become shorter and less predictable. Windfarms and solar cells will not help — they will hinder cold weather adaptation. It is what the UN elitists and their industrial backer wish for — NH Western democracies having the death toll of millions, and the impoverishing of the rest.
