The Sun in March 2018
By Frank Bosse and Prof. Fritz Vahrenholt
(Translated /edited by P Gosselin)
In March our supplier of energy was more inactive than in the previous months. The sunspot number was only 2,5, which is only 8% of what is normal for this month into the average cycle (month 112).
A sunspot was detected only on 6 of 31 days.
An observation made on April 10, 2018, allowed us to say that at approximately 30° southern heliospheric latitude the SDO solar research satellite saw a tiny spot (it was too small to be officially counted as a sunspot) that certainly belonged to the next approaching solar cycle no. 25.
Sunspots are magnetic phenomena. The thermally conveyed plasma at the sun's outer layer generates electric currents. Each of these currents produces a magnetic field. Depending on the direction of the current, the magnetic field is polarized and changes on the sun with each change of cycle.
The SDO instrument is able to determine the polarity of the magnetic field for each sunspot, and provided this image:
Is that the end of cycle 24, some 20 months before the expected month no. 132?
Certainly not. And solar cycle 25 has yet to begin as more spots with the same SC 24 signature are still in the pipeline. Moreover solar cycle 24 could resemble the end of solar cycle 5, see Figure 1. In the months during a minimum, spots can appear that belong to the next cycle, as there is a transition phase where spots of both cycles appear.
The Solar Minimum Has Started
It can still take quite some time before the next cycle makes its debut. Whether the current solar cycle turns out to be both an especially weak one and a short one is still unknown. Historically weak solar cycles have lasted longer than strong ones, It is difficult to say if solar cycle 24 will be an exception. We'll keep you up-to-date!
Next is a comparison of the deviation from the mean (112 months into the cycle) of all the solar cycles recorded thus far since the 18th century:
For estimating the strength of the upcoming cycle 25, we regularly cast a look at the sun's polar fields. The current data are suggesting that solar cycle 25 will be similar to the current solar cycle 24. Thus we have to anticipate that the solar activity will not be retuning to normal levels until at least 2031 - the year solar cycle 25 should end.
The good news is that it is highly improbable the sun will enter a Grand Minimum, such as the one that occurred from 1645 - 1715, the period known as the Little Ice Age.
Comment: Some think differently:
===========================
As Solar Activity Wanes, Arctic Sea Ice Surprises
It is well known that frigid phases on the planet are associated with low solar activity. A number of papers, for example, have linked the Little Ice Age of the 17th century to the low solar activity of the Maunder Minimum. Other published papers link cold winters in Europe to low solar activity as well.
Now it's sure: solar cycle 24 will go down as the weakest in close to 200 years. Thus all the news of massive snow and ice this winter over the northern hemisphere don't come as a surprise for many scientists.
"Melt Season Hasn't Started Yet"
Arctic sea ice has in fact stabilized over the past 10 years. For example Japanese skeptic blogger Kirye of KiryeNet tweeted here: "From the standpoint of Arctic sea ice volume, the melt season hasn't started yet."
At Twitter Kirye posted an excellent GIF animation to compare Arctic sea ice thickness over the past 10 years:
Though a bit below normal, clearly the Arctic ice appears to be rebounding, thus confirming a likely link to solar activity, as has been suggested by numerous scientific publications thus far.
Should solar cycle 25 turn out to be a weak one, then we'll need to worry more about more cold icy winters over the next coming years. And expect embarrassed alarmist global warming scientists to blame it on the "The Atlantic overturning".

PS don't forget to get a small heater for the green house to stop late frost's killing everything you have sown!
Yes, things are likely to get more expensive, but primarily that will be due to an expectation to maintain the same diet. If you are prepared to change your diet to suit the changing environment, then you will source more available and cheaper food. Root vegetables will be more available than wheat, etc. Farmers will adapt, they already see changing weather.
This winter has been harsh and there are still places around the world getting snow now ( [Link] ) . I suggest that your belief that by changing diet and growing different crops in areas less affected by snow and ice is at best naive!
A mini iceage brings multiple problems for farmers, in some areas long lasting snow as in parts of the northern USA and Canada right now! In other areas sodden fields where farm machinery gets stuck in mud and finally, drought, colder weather brings less precipitation, and in some areas crops will fail!
Modern society, especially in towns and cities, is held together by the thinnest of 'glues'! When food starts to disappear of the shelves and prices of other food stocks start to rise there will be riots and supermarkets etc will be ransacked. When the food is gone, then the trouble really begins!
When they mention the lowest solar cycle in 200 years, there is a very good reason for that length of time. It is the barycenter of the sun, influenced by the planets' orbits that appears at this resonance rate which heavily influences solar activity.
Martin Armstrong has discussed the social issues surrounding the climate changes. His article "Maunder Minimum Petri Dish of Political Change" is a good place to start. According to him, the peak of the cycle is in 2032. Yet already we are seeing declines in citrus crops--the mainstay of respiratory disease prevention. It will continue to decline from here, so learn how to raise edible crops in your own artificial environments, and plan for fuel shortages and ridiculous prices.
