The sunspot number for February from SIDC is down again, to 33.1
Here’s the source of that data: http://sidc.oma.be/DATA/monthssn.dat
So far, cycle 24 is significantly lower in SSN number that the last three cycles, in addition to having a delayed start. While the delta of the drop in Feb 2012 is not unusual by itself, it is the lowest observed value of the last three cycles this far into a new cycle.
Compared to the entire data set back to 1749, which I’ve plotted below…
…it shows cycle 24 so far to be on par with cycle 12 and cycle 6 in amplitude.
While this drop in SSN number might appear to some as a signal for a possible peaking of cycle 24, there is other evidence that suggests otherwise. For example the Solar Polar Field Strength. Usually the polarity of the North and South solar hemispheres flips at solar max. As you can see in the graph we are close but not quite there yet. And, it has flattened out compared with previous recent transitions.

Leif Svalgaard also tracks this and here are a couple of his graphs:

Leif has previously suggested that he thinks for solar polar field will see the flip later 2012 or early 2013. We don’t have long to wait.
NOAA’s Space Weather Prediction Center (SWPC) has not yet updated their Solar Cycle Progression page, but will in a few days. In the meantime, here are the SSN and Ap index graphs manually updated with SIDC data to give you an idea of what they will look like compared to the forecast (in red):
The Ap Geomagnetic field index, just like the SSN, is down again, suggesting the sun’s magnetic dynamo is not winding up like it did near the peak of cycle 23 and previous cycles.
We live in interesting times.

The only thing I don’t like about this is that it could give ‘climate scientists’ and other leaders of the CAGW cult an easy exit from their current stance on global warming, without them suffering well-deserved ridicule. Expect statements something along these lines:
“Oh well, how could we have known the Sun was going to cool down like this? We couldn’t have possibly foreseen seen this was going to happen. If that cooling had not happened, we would have been completely right about global warming. So it just goes to prove we were correct about the science all along.”
What scares me most, is that mankind can deal with a little bit of global warming (mostly beneficial, increased rainfall and new crop growing areas), but it will be very difficult to deal with some global cooling (mostly harmful, reduced rainfall and reduced crop growing areas).
—————————————————————
We’ve already had the notion that temperatures may fluctuate down (El Nino) but when the warming comes back; unless we buy(!) into the AGW, it’s going to be even warmer!!!

If at the end of the day, it turns out that climate change is driven primarily by natural variations and that CO2 has little if any driving force, I do not see that scientists will be able to hide behind the sun, and claim that it was not foreseeable that the sun could have any significant input in driving climate variations. A claim of how were they to know, to the layman does not sound compelling.
The reason why at the end game, there will be a blame game is due to the stance that politicians took to address the cAGW threat. When the end game pans out, citizens in the West are going to wake up in a very different world. The price paid will be stark to the citizens of the West and regrettably it will be a price that will be paid for decades to come. It is already too late to roll back the clock and unpick the damage done.
The politicians will have left the West significantly de-industrialised and with high energy costs pushing millions to the brink of fuel poverty. The high energy costs will leave whatever small amount of industry that is left in the West at a significant competitive disadvantage. This will result in long term unemployment issues. Politically, the balance of power which was anyway shifting from the West to China has been greatly hastened and widened. There will be the USA and the BRICS. The UK and Europe will be demoted to sweeping the crumbs dropped from the high table and the USA will find itself marginalised since initially the BRICS collectively but then later China alone will run the show.
Given this backdrop, the citizens of the West will demand answers. It will not be a pretty sight, since the political response was so obviously devoid of merit (it should have been limited adaption only as and when absolutely necessary with no wasteful attempts at mitigation) and the science, when viewed with the benefit of hindsight as will inevitably be the case when judging past events, will appear so flakey and devoid of rigorous scrutiny that severe damage will have been done to science generally and the reputation of scientists. The media because of its own complicity in this affair will attempt to keep a lid on matters but given the diminishing importance of MSM, that will ultimately prove unsuccessful.
What does it matter? As per Dr. Leif Svalgaard’s previous posts, how much does the Sun affect the Earth’s Climate, “not much”, says Dr. Svalgaard.
It appears the only reason to “look” at the Sun is for coronal mass ejections. These may affect satellites. Therefore, “looking” at the Sun is just about scientific curiosity.
One downblip doesn’t necessarily mean it’s going to end up with a lower max; previous cycles have similar downstrokes at similar phases. What’s definitely clear from the graph is that cycle 24 is slower and later than previous cycles.

They are there already. “there will be a flattening or slight fall in global temps over the next few years before global warming restarts afresh and more vigorously”. I think that was Mann and Hansen who said it, although I’m not certain.
What scares me most, is that mankind can deal with a little bit of global warming (mostly beneficial, increased rainfall and new crop growing areas), but it will be very difficult to deal with some global cooling (mostly harmful, reduced rainfall and reduced crop growing areas).
Damn skippy.

think I will be hunting out short cool season seeds for the coming planting.
There are several other cycles that had huge up and down swings like this. This is not that abnormal.

Has anyone noticed that the Solar Flux has dropped to below 100? Could SC24 be waning?
No, weak cycles have shown erratic behaviour during their maximum years, e.g.
http://www.leif.org/research/SC14-and-24.png”
The Solar Flux seems a more stable metric than sun spots. It looks like a DC offset, like the top of a pyramid that’s half buried.
When what little SC24 has to show, is it possible the Solar Wind could just stop?
http://science.nasa.gov/science-news/science-at-nasa/1999/ast13dec99_1/
SC24 has peaked. You heard it here first.
I noticed on the Solar Page that Total Solar Irradiance (TSI) -F10.7-MF-SSN-Solar Activity Plot seems to show a peak then a plummet.
Any significance Leif?
It looks like it is following Leif’s prediction pretty well:
http://www.leif.org/research/TSI-SORCE-2008-now.png
Oh where oh where have the sunspots gone?
Oh where oh where could they be?
Wth their number so small
When we are near the peak
Oh where oh where can they be?
What I see (qualitatively) in past cycles is there seems to be a much higher std. deviation around the trend line as you approach solar max & that the scatter (visually ) appears to have a ~ normal distribution about the trend mean. If this latest swing up & down is representative, I would guestimate the trend peak will be somewhere in the 60-75 range, which would be substantially lower than past cycles

Says it all…
I just got an email with pics of Russia in winter… Would those north of the Mason-Dixon line look like that? Where are all the Canadians going to live? Northern Europeans?
Avoid the rush! I’m moving south now!
If total energy is the sum of sunspots plus some factor times squared mag field, the sun ihas been in a real slump for the past decade!
(In a harmonic oscillator like a weight bouncing on the end of a spring, total energy is the sum of potential energy (determined by position of the weight) and kinetic energy (from the velocity of the weight). Here sunspot numbers – or their square root times an unobserved sign – and mag field seem to be playing these two sinusoidal roles.)

What are the conditions like? I have been off air for so long (travel too much) I have no recent reference.

So, the alarmists were right, after all … in the 70’s, when they were calling for the next ice age. They should have stuck with their original story. A lesson all crooks and grifters eventually learn the hard way.

“Because the Only Good Progressive is a Failed Progressive”
Surely, all that lovely CO2 will prevent any discomfort from a solar minimum? After all, it’s the CO2 responsible for ALL warming, isn’t it?
Incidentally, I have a great design for a new oven – connect CO2 fire extinguisher to a box, place food in box, switch on gas – hey presto, hot food. (Should I add a “sarc” just in case?)

Lief, Re WSO polar fields. I presume that this is related to the slowing of the circulation velocities? Does a field reversal have a precedent in documented science? Is is speculated that one or more of the minimums may have yielded a field flip, with the funk?
The solar polar fields reverse in every solar cycle, usually near maximum.
Being in Northern Vermont, I was cheering on the gradual warming of our hemisphere, but I’ll adapt to whatever comes along. Dr. Jerry Pournelle has been a rational and reasoned skeptic for many years and has recently taken up the topic again with his readers.
His questions and assertions are worth reading at Chaos Manor.
Cosmic ray flux looks kinda like a minimum too. http://cosmicrays.oulu.fi/webform/query.cgi?startdate=1964/01/01&starttime=00:00&enddate=2012/03/02&endtime=04:45&resolution=Automatic%20choice&picture=on
Has anyone looked at monthly Sun Spot Numbers for November and December and compared them with minimum temperatures for the following months January and February?
There is a good match between minimum Sun Spot Numbers and minimum NH temperatures going right back through the data records.
Sun spot numbers are matching individual temperature records from the northern hemisphere during winters, I would guess that the input from the sun was driving temperatures.
Did someone really say that the Sun has no effect on the Earth? it sounds to me like they may have been took out of context, because I don’t believe someone could make such an idiotic comment and actually mean what it infers.
From watching Anthony’s solar reference page, it seems to me that the end of the month was quieter than the beginning. Don’t know if that means anything.
