@ dolanbaker , I mentioned the first C 25 sunspot a bit further up ,
the source is from the official body , it's very scientific ,
it is from the new cycle because the polarity is inverted
the only query is that it appeared at quite a low latitude ,
usually a few form close to the solar poles and after a few years there is more and more toward the equator
their frequency is seen in the "butterfly diagram "

Thanks I knew I'd seen it somewhere.
It's that low latitude that that increases the risk of it being a false positive, otherwise cycle 25 could end up seriously overlapping 24.

On the other hand maybe having two opposing cycles together may be the cause of the low sunspot count in the first place, one cancelling out the other.

A thought that provokes far more question that I could possibly answer.
Ronald Coase, Nobel Economic Sciences, said in 1991 “If we torture the data long enough, it will confess.”

You are in good company
The scientist are pretty sure they can locate the sun ,
there are some good observations of its surface and some hypothesis of its interior
as for its precise working , it's a bit of a dog breakfast

They are based on computer models that use the current cycle as if it were a baseline, or so it appears. If you look at the available history going back to the 1600's there was a 100 year low cycle at the start of the 19th, 20th, and now 21st century. The next cycle after each of those low cycles however was much closer to an 'average' cycle. Looking at this I believe cycle 25 will be close to average no matter what the computer models are saying.


The problem is not the use of computer models. The problem is the lack of governing dynamical equations for the Sun that can be used to simulate its evolution. It is a highly nonlinear MHD plasma system. We cannot measure its interior since it is opaque to EM radiation (worse than the electrolytic oceans on Earth) and we do not understand the various dynamical scales at work in this system so we can't even start to approximate. On Earth the Navier-Stokes equations do a very good job of describing the atmospheric and ocean systems. We can readily simulate synoptic and mesoscale structures that are important for the atmospheric evolution. In the case of the oceans we have a problem of resolving the small eddy scale which exerts a dominating influence on the dynamics. But high resolution ocean models are available. Nothing of sort exists for the Sun and we only have empirical, aka black box statistical, models.

The warmists are going to love this ,
as a upstanding proponent of the Solar influence on climate ,
and having some feeble claims to intellectual honesty .
this must be said ,
the relationship between total solar irradiance and the Earth surface temperature is very weak
the present low sunspot count has not any correlation with present day global temperature .

it doesn't affect my opinion that warmists have the scientific integrity of chickens fed on rubbish

Thanks for the concession, spark.

Do you have any new theories you care to share with us, or any correlations you are tracking these days. One thing I have always been impressed with about you is that if you see that a correlation you have hypothesized does not pan out, you are ready to admit it, rather than holding on to it in spite of the evidence.

Was there something in particular that convinced you on this one?
