Measurements by spacecraft and ground-based observatories agree that the sun’s north and south magnetic poles are rapidly weakening. This could lead to a complete reversal of the sun’s global magnetic field before the end of the year.
From the National Solar Observatory (NSO):
The Sun is about to turn upside down – magnetically speaking, of course.
In recent months, we’ve seen an uptick in explosive solar events from dramatic X-class flares to Coronal Mass Ejections (CMEs), to powerful geomagnetic storms and a record-shattering sunspot count in June. The Sun may appear to be a raging inferno to the general public, but to solar scientists, it’s business as usual.
An active Sun was expected and these events are indications that the current Solar Cycle 25 is reaching its peak in activity, known as Solar Maximum. The Sun typically follows 11-year cycles bookended by periods of Maximum (high activity) and Minimum (low activity). When this cycle reaches Maximum, the Sun will begin to “quiet down” and decrease in activity as it transitions to Solar Minimum over the next decade. Once reached, Solar Cycle 26 will begin.
The Sun is busy, but one of the exciting developments is the reversal of its magnetic poles. Like Earth, the Sun has two magnetic poles, one positive and one negative. These poles change polarity, or magnetically flip, but unlike Earth’s poles that reverse roughly every 300,000 years, the solar poles flip about every 11 years!
The Sun’s polar field reversal is the major hallmark event that signals the end of a solar cycle’s Maximum period and ushers in the transition to Minimum. After the reversal, the newly established polar field will determine the strength of the next solar cycle. While the polar field reversal doesn’t happen in a dramatic display of firepower, it is an enormous global change with many consequences. For example, this is the only instance where activity like filament eruptions and CMEs – known to negatively impact Earth’s power and communication networks – can happen at any latitude on the Sun, including its poles.
The reversal happens when the Sun’s polar magnetic fields are weakened and replaced with a new field of the opposite polarity (e.g. going from positive to negative). The reversal is driven by sunspots, the magnetically-complex structures that create active regions where flares and other solar events originate. As sunspots emerge from the Sun’s interior in polar-opposite pairs, plasma flows rearrange their magnetic fields, stretching, weakening, and emphasizing the biases of their polarities. These weakened sunspot fields are carried by plasma flows towards the poles. The newly-arrived field tends to be of opposite magnetic polarity to the existing polar field, and when opposite polarities come into contact they destroy each other. This process comes to a head at the peak of the solar cycle, when enough opposite-polarity fields arrive at the poles, destroying the polar field, and replacing it with a new polar field of the opposite magnetic polarity.
While polar field reversals vary in speed in timing, it generally takes a year or two to complete, but it varies. Solar Cycle 24’s north polar field took nearly five years to reverse!
On Earth, the effects of the polar field reversal are rarely felt, but the solar community is paying close attention. Orientation of magnetic fields in CMEs may be affected by large-scale magnetic fields. Thus, having negative (southern) polarity fields at the Sun’s North pole and positive (northern) polarity at the South pole would create magnetic topology opposite to Earth’s magnetic field. During that period, on average, the CMEs will have a slightly larger impact on Earth as compared with the period when the polar fields have opposite polarities. Thus, one should expect that after the polar magnetic field reversal and rebuilding, on average, the geomagnetic storms would be stronger than in the declining phase of Cycle 24 and the rising phase of Cycle 25.
The NSO operates the NSF’s six, ground-based solar telescopes that make up the GONG suite of ground-based solar telescopes. GONG stations are strategically located around the world to maintain a near round-the-clock surveillance of the visible Sun and have documented over 20 years of solar data. Observing the progress of the Sun’s polar migration is one of its many responsibilities.
The Sun’s polar fields are difficult to measure from Earth, given that the poles tilt towards us at only 7 degrees, at most. We can only see one pole at a time, but its magnetic field extends to about 30 degrees from each pole, bringing it into GONG’s view. GONG uses its ability to take continuous measurements of the Sun to study the progression of polar field reversals. This provides an important predictive capability – a stronger polar field could foreshadow a larger, more powerful solar cycle with more sunspots, flares, and other solar activity. Thus, providing us with an idea of what to expect during the next solar cycle.
GONG uses direct observations of the magnetic fields to understand when the polar field is reversing. Another indication is the position of polar crown filaments (a “fibrous” structure consisting of plasma and magnetic field lines found in the Sun’s upper latitudes), which GONG has recently detected in the image below.
While the solar poles will “flip”, rest assured, there’s no need for us to flip out. This is a naturally occurring process on a massive scale that’s happened throughout the Sun’s lifetime. A polar field reversal would indicate a healthy solar cycle and that things will continue as it was in the past, whereas a lack of a reversal would indicate potential major changes to the solar cycle. As we anticipate the polar field reversal, we can expect to see a larger number of X-class flares, larger CMEs, and stronger geomagnetic storms – stay tuned for the next update!
Having been so ‘busy’ is that a factor in recent warmth ?
Yes, solar cycle 25 has far exceeded NOAA and NASA estimates – sunspots a plenty as is flux and CMEs etc, it’s going to be a good one
Aurora have been seen in the English Midlands on three or four occasions in the last month or so, we rarely see them this far south even once.
Isn’t it rather early in the cycle for the eventual flip?
We’re only about 3 years into the cycle
You might want to consider Australian estimates

The only thing for certain are both the N and S components are right on top of each other that makes count look higher at moment(than…) The real question is total count over entire cycle. See the butterfly patten in link in my other post. This pattern does not indicate a extreme cycle at this point. The next months will be interesting. Compare butterfly patters over cycle history. Making no prediction, too early in cycle with N/S perfectly aligned.
I long to see them, but light pollution is the problem 🙄
I guarantee that this won’t have any effect on Earth and the climate. /s
It will have more effect than the climerati understand or acknowledge
The sun’s magnetic fields flip approximately every 11 years, defining the solar cycle – the switch happens around the peak of solar activity or the time we call solar maximum – this reversal tells scientists that the second half of the solar cycle has begun
The flip will likely cause more extreme space weather, including aurora
The Earths magnetic poles are also on the move – we could be due a double flip, now that would be interesting
THe Earth’s pending flip is going to take many more years to occur, perhaps decades,
2 birds in one
Just spinning subject
Best place to track sun cycles these days..
http://solarwww.mtk.nao.ac.jp/en/solarobs.html
They have plots of N and S components along with real time butterfly plot
Also good Korea site on subject, do not bother with nasa/noaa spin these days…
You do realise that is not a secure site? Best left alone unless your computer likes viruses
I have a tablet that I pretty much only use for browsing. It is also got a firewall that actually shuts Google down first a d foremost. Do not browse with important computers. Do you know of any malicious activity from this site?
A long, long time ago
On a server far away
Wattsupwiththat was under an attack

Dun dun dun dun de dun dun de dun dun dun dun dun de dun….
Please define “not a secure site” with special attention to how visiting such a site is different than a “secured site”(define).
If the average solar cycle is 11 years and there is only 20 years of ‘good’ observational data, Ain’t this a situation where there is a too small a data set to make any reasonably accurate prediction?
Just asking for a friend.
…but taken in conjunction with the various, often excellent records of solar activities and so forth, an extremely interesting picture is emerging. I believe Rud Istvan is the bloke with the solar data running out his ears? He bin saying this shtuff for years…
There’s been good solar data taken for a number of decades, the difference is that the data taken over the last 20 years is nearly continuous (24 hours/day) where previously the data may have had several hour gaps per day.
No doubt the climate alarmists will jump on this information and tell us that excess fossil fuel consumption on Earth has had more far-reaching effects than originally thought. So we’d better switch to wind and solar before other stars are also affected.
Were all gonna die!
We have to stop using fossil fuels that is the only way!
/sarc
Ayup, sometime in the next 77 years, between now and 2100 over 7.8 billion people will die
I blame the industrialists. If it wasn’t for them and their activities over the past 150 years it would only be about 1 billion over the next 77 years….
Is this coming from the same lie spewing f*cks who tell us humans are destroying the climate? That same anti-human, lie spewing c*nts? Nothing they have ever said is real, or EVER happened. Why do you keep giving them legitimacy? The f*ck is wrong with you?
So this polar flip is a GONG show then?
But why the scary headline?
Because as stated further down in small print “ but unlike Earth’s poles that reverse roughly every 300,000 years, the solar poles flip about every 11 years! ”
A nice piece about the every day story of solar activity. Basically, everything is normal and might provide a bit of variation but just like the weather here on planet Earth, sometimes its quiet and sometimes, it is active.
Talking of which, today there is not a breath of wind here in central UK. This follows a period of strong ‘Saudi Arabian’ wind conditions over the previous three weeks. A beautiful golden sunrise illuminating the morning clouds and a lovely warm autumn day promised.
Life can be so pleasant, when we stop being anxious about normal variation…. 🙂
I have various objections to the exact wording of much of this post (…The reversal is driven by sunspots,…) but interesting none the less.
Of course, not mentioning the role of Jupiter and Saturn, at the least, makes this an incomplete report.
Actually explaining that role, that I await with excitement and trepidation. ( If Electric Theory is correct, the sun could actually switch off at a (galactic) moment’s notice).
But yeah, subterranean weather, which seems to correlate with solar weather, seems to majorly influence atmospheric weather. The least that can be said for the climastrologists; they are forcing us to learn, and in refuting them we are furthering more science than just meteorology.
There’s a reason why Jupiter and Saturn aren’t mentioned. They play no role whatsoever, and Electric Theory is not correct.
You’ve been lurking around this site for how long? And you still don’t know about sunspot cycles synchronising with those two orbits and conjunctions?
I take your opinion on an electric universe is as well informed?
oh,
i almost forgetted: So does the flipping of the magnetic thingey….
Isn’t there a Grand Solar Minimum going on as well?
The above article is informative and, to its credit, states in the concluding paragraph that
“While the solar poles will “flip”, rest assured, there’s no need for us to flip out. This is a naturally occurring process on a massive scale that’s happened throughout the Sun’s lifetime.”
Of note—and not mentioned in the above article— is the fact that the Sun’s magnetic field reverses every 11.4 years on average. Long term solar observations document that the periods of the Sun’s “sunspot cycle”, commonly know as the Schwabe cycle, have ranged from 8 to 15 years, and during the Maunder minimum disappeared for more than 80 years!
Story tip
The Apollo 15 heat flow experiment failed because their drilling equipment could not drill deep enough to measure the moons interior heat flow. They left their thermocouple array at or near the moon’s surface, thus measuring the moon’s surface temperatures. These data showed that the moon’s temperatures increased from 1971 until readings ended in 1974.
When NASA scientists reviewed these data, they suggested that the rising temperatures on the moon in the 1970s (when earth’s atmosphere was warming too) must have been caused by humans too. The NASA report suggested that the astronaut’s footprints in the lunar soil would have reduced the albedo effect reflection of the lunar dust, thus causing the soil to absorb more solar energy.
But if tests show that this could not explain the temperature change on the moon, what else? Can cows burping and farting be that damaging? Is Mars safe from cows farting?
It’s not April 1, is it?
