Solar Cycle 25

[hankslincoln]

I read on wuwt that the latest sun spot had a reversed polarity from sc 24.

Apparently yes, however all the information was provided by Leif Svalgaard who is a solar scientist, and quite a renowned one at that. Not sure any of us mere mortals can do much more then agree with his findings and wait and see!!

A new SC25 group?

A sunspot group of the new solar cycle (SC25) emerged around noon on 9 April, and had disappeared by noon of the next day. It concerned a tiny region at a latitude of -31° (i.e. in the southern hemisphere), and has not received a NOAA number yet. It was observed by the Mount Wilson Observatory on 9 April and by a number of observers from the SILSO network on 10 April. It would have been only the third numbered sunspot region of the new solar cycle (see images underneath), and the first SC25 group at high latitude with the correct magnetic orientation. Indeed, the previous SC25 groups were observed in December 2016 at a rather moderate -23° (NOAA 2620), and in January this year there was NOAA 2694 at a high latitude (-32°) but with the "wrong" (SC24) magnetic orientation. More on this odd configuration in this STCE Newsitem. In all three cases, it concerned tiny sunspot groups lasting only a day or so.

SC25 is on it's way....

So, 24 spotless days and now 2726 which is practically invisible and right on the equator. Probably would not have counted 75 years ago... Still it Being November 2018, exactly nine years into cycle 24, and a couple of years from the minimum??? With 60% spotless day count for the year and climbing steadily we could be in for a long quiet time...

Correct me if I'm wrong, but we have not seen a high latitude reverse polarity (from cycle 24) spot yet? I think Leif has a prediction out for 25, a moderate cycle, a bit stronger than 24, but I can't remember if he predicted when the 24/25 minimum would be...

17 Nov 2018, a short lived spot in the Northern hemisphere. Did not last long enough to be numbered. Did have a cycle 25 profile and was mid-to high latitude. The magnetic profile was twisted about 45° off of horizontal...

Not sure any of these three active regions are true cycle 25, or just random magnetic knots showing briefly at the surface...

Time will tell. Popcorn futures are up.

Dr. Svalgaard?

Hmmmm?

One of the strongest Solar Cycles we've witnessed eh?

So what of this promised 'maunder like min' I've been being promised these past decades?

And, if a deep min causes 'cooling' then what does a 'strongest' cycle mean for Global temps (we know the potentials for Satellites & 'driven currents' here on the surface frazzling irreplaceable electrical infrastructure components....or did we build enough spares to go around now?)

If this newly recognised '22 yr magnetic cycles', offset from the 11 yr 'Solar Cycle' continues to gain acceptance then we've a doozy in store eh? 210 to 260 instead of a piffling 115 for the peak value....big change eh?

Nasa had been out with a prediction the upcoming cycle was going to be weak and ideal for exploration.

“There is no indication that we are currently approaching a Maunder-type minimum in solar activity,” Upton said. But even if the Sun dropped into a grand minimum, there’s no reason to think Earth would undergo another Ice Age; not only do scientists theorize that the Little Ice Age occurred for other reasons, but in our contemporary world, greenhouse gases far surpass the Sun’s effects when it comes to changes in Earth’s climate.
