There is something strange with the sun.
Some of the most powerful eruptions our star is capable of have erupted so far.
An eruption of the Sun is not strange. As it goes through periods of high and low activity, it erupts frequently.
A solar scientist will tell you that even this isn't all that strange.
"We can't reliably predict the cycles of the sun," said Michael Wheatland, a solar astrophysicist.
The magnetic fields seen at the surface as sunspots and flares are not fully understood by us. The inaccuracy in the prediction is unsurprising.
I think it's surprising. If we don't expect to be good at predicting solar cycles, we need to rethink how we do it. If we base our predictions on the wrong metric, what would we do?
The impact of solar cycles is not well understood. They seem to be connected to the solar magnetic field, which arcs across the surface of our Sun in twists, swirls, and loops.
The Sun's magnetic poles change every 11 years. The switch coincides with a peak of sunspot, flare, andCME activity.
Sunspots tend to appear in bands on the sun.
After this reversal activity slows before ramping up again. The 25th of the current cycle is where we are now.
The number of sunspots seen on the Sun is one of the metrics used to predict activity cycles. These are temporary areas where the magnetic fields are strongest. The regions are cooler and dimmer than their surroundings due to the magnetic field.
Predicting solar cycles based on how many sunspots we have is a problem.
The sunspot cycle isn't the main thing. He told Science Alert that it was a secondary thing. Solar activity is portrayed as the primary in the way the canon is written.
The underlying Hale cycle is the primary cause of the problem. The sunspot cycle is just a small part of the larger picture.
The Hale cycle was discovered by an American astronomer. The time it takes for the poles to swap twice is part of the sunspot cycle.
The 11-year cycles are observed in many phenomena. The changing magnetic polarities of both sunspots and solar magnetic poles are shown.
The odd- and even-numbered solar cycles have different Cosmic Radiation Wavelengths. The sun's magnetic field has been attributed to this.
We don't have a good idea about what goes on in the Sun. It is thought that the solar magnetic field is created by a rotating, convecting, and electrical conducting fluid that converts energy into magnetic energy, spinning a magnetic field out into space around the sun.
What causes sun spots? They are related to the Sun's rotation. The poles are slower than the equator. If straight magnetic field lines were to be dragged along with the rotation, they would become stretched and tangled, causing sunspots.
The magnetic field is thought to be passive.
There is a very complex system inside the sun. He said that like all physical systems, we make simplifications to try and understand what's happening.
The fluids on the Sun were larger than the magnetic fields. The rotation drives circulation, the heating of the atmosphere drives circulation, and with all this circulation going on, the magnetic fields just get dragged around with the circulation.
The animations that show this effect are very similar to the observational data of sunspots. The model was created to explain exactly what happened.
The sunspot are caused by the magnetic fields of the Hale cycles.
There was an overlap in butterfly diagrams in sunspot data in 2011. Sunspot appearances by latitude are plotted in these graphs.
The animation shows how a new wave terminates at the equator. Scott McIntosh is a driver for the NCAR.
The researchers pored over as much historical sunspot data as they could after they spotted this.
The overlap continued to show up. The appearance of the next sunspot can be seen at the mid-latitudes as the sunspots appear closer to the equator.
The sunspot cycle is not driven by the bands of magnetic activity that make their way across the sun in cycles. The cycles can interfere with each other.
There is a period of minimal sunspot activity following the result of this.
The sunspot cycle is caused by interactions between the larger magnetic cycles. It's similar to an interference pattern. The magnetic fields are trying to cancel each other.
The results of the interference pattern have led to predictions of the current solar cycle that are more in line with current observations than official predictions.
It is all theoretical at this point.
We don't have enough information to tell us what causes the bands of magnetic activity across the Sun, but the researchers think it might be gravity waves.
The forecast for cycle 25 is closer to the official one than it is. It's not based on a model at all. I don't think it has more power than other approaches to prediction.
It will take time to get more data. It means looking at the Sun's high latitudes as a new cycle forms.
The European Space Agency's Solar Orbiter will swoop over the solar poles about the time a new cycle begins.
There is something to the fact that his team's prediction is close to how solar cycle 25 has played out. The team's ideas need to be looked at more closely.
He said that they have been spot on for about 10 years.
The solar cycle gave an opportunity. We need to take a second look at how stars make magnetic fields if we end up being close.
It might be closer to the way that we're seeing it. It could be a mixture of the two. It's likely.
The paper on the solar cycles was published in the journal.
