Forecasters keep eye on looming 'Solar Max'
December 29, 2010 by Annie Hautefeuille and Richard Ingham
A NASA image of an eruption on the Sun. The coming year will be an important one for space weather as the Sun pulls out of a trough of low activity and heads into a long-awaited and possibly destructive period of turbulence.
The coming year will be an important one for space weather as the Sun pulls out of a trough of low activity and heads into a long-awaited and possibly destructive period of turbulence.
Many people may be surprised to learn that the Sun, rather than burn with faultless consistency, goes through moments of calm and tempest.
But two centuries of observing sunspots -- dark, relatively cool marks on the solar face linked to mighty magnetic forces -- have revealed that our star follows a roughly 11-year cycle of behaviour.
The latest cycle began in 1996 and for reasons which are unclear has taken longer than expected to end.
Now, though, there are more and more signs that the Sun is shaking off its torpor and building towards "Solar Max," or the cycle's climax, say experts.
"The latest prediction looks at around midway 2013 as being the maximum phase of the solar cycle," said Joe Kunches of NASA's Space Weather Prediction Center.
But there is a prolonged period of high activity, "more like a season, lasting about two and a half years," either side of the peak, he cautioned.
At its angriest, the Sun can vomit forth tides of electromagnetic radiation and charged matter known as coronal mass ejections, or CMEs.
This shock wave may take several days to reach Earth. When it arrives, it compresses the planet's protective magnetic field, releasing energy visible in high latitudes as shimmering auroras -- the famous Northern Lights and Southern Lights.
But CMEs are not just pretty events.
They can unleash static discharges and geomagnetic storms that can disrupt or even knock out the electronics on which our urbanised, Internet-obsessed, data-saturated society depends.
Less feared, but also a problem, are solar flares, or eruptions of super-charged protons that can reach Earth in just minutes.
In the front line are telecommunications satellites in geostationary orbit, at an altitude of 36,000 kilometres (22,500 miles) and Global Positioning System (GPS) satellites, on which modern airliners and ships depend for navigation, which orbit at 20,000 kms (12,000 miles).
In January 1994, discharges of static electricity inflicted a five-month, 50-million-dollar outage of a Canadian telecoms satellite, Anik-E2.
In April 2010, Intelsat lost Galaxy 15, providing communications over North America, after the link to ground control was knocked out apparently by solar activity.
"These are the two outright breakdowns that we all think about," said Philippe Calvel, an engineer with the French firm Thales. "Both were caused by CMEs."
In 2005, X-rays from a solar storm disrupted satellite-to-ground communications and GPS signals for about 10 minutes.
To cope with solar fury, satellite designers opt for robust, tried-and-tested components and shielding, even if this makes the equipment heavier and bulkier and thus costlier to launch, said Thierry Duhamel of satellite maker Astrium.
Another precaution is redundancy -- to have backup systems in case one malfunctions.
On Earth, power lines, data connections and even oil and gas pipelines are potentially vulnerable.
An early warning of the risk came in 1859, when the biggest CME ever observed unleashed red, purple and green auroras even in tropical latitudes.
The new-fangled technology of the telegraph went crazy. Geomagnetically-induced currents in the wires shocked telegraph operators and even set the telegraph paper on fire.
In 1989, a far smaller flare knocked out power from Canada's Hydro Quebec generator, inflicting a nine-hour blackout for six million people.
A workshop in 2008 by US space weather experts, hosted by the National Academy of Sciences, heard that a major geomagnetic storm would dwarf the 2005 Hurricane Katrina for costs.
Recurrence of a 1921 event today would fry 350 major transformers, leaving more than 130 million people without power, it heard. A bigger storm could cost between a trillion and two trillion dollars in the first year, and full recovery could take between four and 10 years.
"I think there is some hyperbole about the draconian effects," said Kunches.
"On the other hand, there's a lot we don't know about the Sun. Even in the supposedly declining, or quiet phase, you can have magnetic fields on the Sun that get very concentrated and energised for a time, and you can get, out of the blue, eruptive activity that is atypical. In short, we have a variable star."

I was comparing "solar storms" to "earth storms" and comparing an actual quiet storm season on Earth, during which one catastrophic storm still occurred, to a projected quiet storm season on the Sun being presented as indicating little danger of catastrophic events to come. Yes, different celestial bodies and different processes involved, but both have cycles of calm and storms, and in both cases, IMO, a quiet season brings with it no guarantees of freedom from one catastrophic event. That's my whole point. Solar storms DO occur, and the danger, great or small, to our 21st century electronic world is real, so IMO the best approach would be for those responsible to "harden" the infrastructure so any storm may become just a momentary blip, not a catastrophe.

As for not being able to do anything about it, that is not true. If electrical devices are disconnected and shut down the damage is localized. The change of flux through a loop determines the voltage and if the loops are small the voltage spike is low. In like manner satellites can be hardened. This is actually going on now by those who understand the problem and could be in place within 25 years.

You must not understand that the sun is being watched 24/7 from multiple satellites. If you go to "Spaceweather.com" you can see that they make daily observations of possible events - and NASA and every other space observatory is watching for this kind of event. If it happens the alarms will go off within minutes and things will start shutting down. When SH mentioned 5 years for the protection to be in place I was surprised. The 25 years I had used was based on a study I saw a few years ago that said that coordinating the shut-down might take days (too long) until the grids world wide are able to react automatically. My guess is that most of the world won't be there for at least 25 years but SH is probably right about the G7.

On the other hand, it would make sense for there to be an incredibly dense core of heavier elements fusing at the center of stellar cores. It wouldn't take much heavy element fusion to create a good deal of energy.

As far as we know, it's not a danger to living things on the Earth's surface. Our magnetic field and atmosphere protect us from the worst of it. Of course, that has to be said with the understanding that even 'normal' solar radiation is somewhat harmful to living things. Astronauts can get a lot more than the usual dose of radiation during a storm though. They can even sometimes see optical effects in their eyes. Space walks are canceled and astronauts on the ISS are told to go to the center of the station when storms happen.

Well the problem is the stability of Iron. Iron is the first element where the energy required for fusion jumps exponentially. As stellar fusion and nucleosynthesis are effectively driven by gravity, in lower mass stars like our sun, the calculations do not show that enough energy is present to fuse iron in any significant quantity.
Dec 30, 2010
Rank: 1.5 / 5 (2)
I agree, but I just don't think that it is realistic to expect that NO iron fusion occurs whatsoever. It would of course be extremely rare compared to the other fusion occuring, but gravity should be doing a nice job sorting all the elements. I would expect that if someone could freeze a star, cut it in half and look at the very center, you would find a lot of heavy elements. -- alot meaning on a human scale, like 10lbs of cobalt or something

If Oliver's theory is assumed to be true, then what does that say about the composition of mass in solar systems, and how does that relate to the observed composition of our solar system? Should there be more or less iron than what we see? Should there be more or less hydrogen? I don't have any idea what the actual answers to those questions are, so please don't think that I'm suggesting one view over another. My point is that we should be able to caclulate the expected values and compare them to observations.
It would seem to me that fusion of heavy elements would lead to the eventual conversion of most light elements into heavy ones. I guess the rate and magnitues are the questions.

Ah ofcourse, the fact the aurora is visible during the storms would mean our magnetic field was doing its job. Suppose it could be dangerous if a storm coincided with a magnetic pole flip but the chances of that must be pretty slim lol.

No. We have nuclear evolution completely backwards.
We assumed that nuclear matter was fusing together:
H => He => C => . . . Fe => Neutron Star.
Instead, nuclear matter is fragmenting:
Neutron Stars =(emit neutrons=> n =(neutron-decay)=> H
The Sun and other stars release H in the solar wind as a waste product!

He keeps switching back and forth on Neutron star vs iron core. Won't even acknowledge the question WHICH is it he means. Oliver does not like inconvenient questions. He ignores them hoping they will go away. Not going to happen. I am pretty sure I will outlive him. He looks to be in LOUSY condition.
I suspect that when he says neutron star he really means an iron star. He insist that black holes are impossible and ignores the math showing that they must occur if you pack in enough mass. So my guess is that he doesn't believe in actual neutron stars just an iron equivalent. That avoids the problem that the sun is too small for a neutron star. Why he doesn't just say so is just more of his Crank peculiarities. Which is his good side.

There are no iron stars out there. Just stars with some iron such as ours.
Neutron Stars =(emit neutrons=> n =(neutron-decay)=> HWhich is wrong since bound neutrons don't decay. No one has seen it happen. EVER.
It doesn't help that you can't seem to decide whether its a neutron star or iron in our own Sun. You switch wildly on that.
