Solar cycle sparks doomsday buzz

Alan Boyle writes: Don’t panic over those reports that solar storms could cause high-tech disruptions in 2013. But don’t ignore them either. That’s the word from NASA Headquarters' top guy for solar science.

Concerns about the potential for an unprecedented assault from space were stoked last week by a report in London's Telegraph, warning that a super storm could cause "catastrophic consequencies for the world's health, emergency services and national security unless precautions are taken."

The warnings focus on the 2012-2013 time frame, because that's when the 11-year solar activity cycle is expected to peak. Back in 2006, solar scientists said the coming peak, known as solar maximum or "solar max," could be 30 to 50 percent stronger than the last one, based on a computer model that looked at how plasma circulates between the sun's equator and its poles.

Since then, additional reports have added to the concern: In 2008, a National Academy of Sciences study said a severe geomagnetic storm could cause $2 trillion in damage and require as much as a decade of recovery time. In comparison, the damage estimate for Hurricane Katrina is a mere $80 billion or so.

Amid all the hype about a 2012 Maya apocalypse, there's been increasing talk about the potential for a solar superstorm on the scale of 1859's "Carrington event," which shorted out telegraph wires, sparked fires and set off auroral displays as far south as Cuba. The fear is that the damage would be more severe in this world of GPS navigation, satellite communications and mobile devices.

The Telegraph's article quoted Richard Fisher, the head of NASA's Heliospheric Division at the space agency's Washington headquarters, as saying that a superstorm would "cause major problems for the world."

"It will disrupt communication devices such as satellites and car navigation, air travel, the banking system, our computers, everything that is electronic," he told the Telegraph.

When I caught up with Fisher, his forecast was less dire, and less definite: He told me it's far too early to say just how strong the next solar maximum will be. In fact, some experts are now predicting that the intensity will be well below average, based on the fact that the sun has been unusually quiet in recent years.

"The next maximum is anticipated to be somewhere around the lowest ever seen to a little bit higher than the highest that's ever been seen," Fisher said half-jokingly. "I think it was Yogi Berra who said ... the problem with predictions is that they all take place in the future."

But Fisher doesn't joke about the need to be prepared for the potential disruptions caused by space weather. A bad solar storm could easily have a negative impact on everyday life. For example, air traffic over the North Pole has increased dramatically since the previous solar maximum in 2001. If severe geomagnetic storms were to sweep past Earth, those flights would have to be shifted farther south to guard against communication disruptions. This year's Icelandic ash mess suggests how a situation like that might affect global travel and commerce.

"It has a fairly large economic impact on an airline if you have to divert an airliner," Fisher noted.

Fortunately, the methods for predicting space weather have improved over the past decade or two. Satellites such as the Advanced Composition Explorer can spot the signs of a geomagnetic storm up to an hour before it hits our planet, providing valuable lead time for power grid operators. (A space storm in 1989 sparked a nine-hour electrical blackout in Quebec, affecting 6 million customers and costing the power company more than $10 million.) Other observing instruments, which measure seismic activity originating on the far side of the sun, can provide a couple of weeks of warning about active sunspot regions.

So how bad does Fisher think things can get in 2013?

"I think there's a relatively high probability that there will be a solar event that will have some effect over hours to tens of hours. That's pretty high in the next 10 years," he told me. "I think that it's a low probability but a very high-impact circumstance for a large solar event that disrupts infrastructure for periods of longer than a day or two."

He doesn't advise preparing for Armageddon, but he does suggest that you have an emergency supply of food, water and the other things you need to weather a disaster. Which is good advice whether or not a superstorm hits in 2013.

"In modern life, you want to understand how vulnerable you are," Fisher said. "A good big winter storm will knock out the local power delivery for hours to a day or two. I keep a little water around the house in case that situation happens. There are alternate systems for providing power to hospitals, critical records and things like that. I think it'll be inconvenient, as opposed to ... well, not necessarily deadly, for goodness' sake."

Update for 9:15 p.m. ET: Just how vulnerable are our satellite-based communication systems to outbursts from the sun? For another perspective on the superstorm hype, I checked with Joseph Mazur, associate director of the space science department at The Aerospace Corp.

"At Aerospace, when we're working with our national security customers and commercial customers and even NASA, we're really focused on the space systems working throughout the extremes of the space environment," Mazur said. "So we do our work before the spacecraft is launched."

The Aerospace Corp. works with satellite builders and operators to make sure their spacecraft can stand up to the worst-case scenario for space weather. That scenario is based on previous observations, and not on hypothetical speculation about how bad things might have gotten in 1859. "There's not much information about what the specific hazards were like for that event. ... In mission design, there is currently no way to account for an event that exceeds the previous worst case," Mazur said.

Mazur wanted to clear up a couple of misconceptions about outbursts from the sun: First of all, he said, "I really have a problem with the whole phrase 'solar storm,' because in the public literature, it connotes something that comes from the sun. ... The problem is that you can't just put all of space weather into one term." In reality, space weather takes in a spectrum of phenomena - ranging from outbursts of radio interference that travel at the speed of light, to eruptions of electrically charged particles that take more than an hour to reach Earth and interact with our planet's magnetosphere.

Another misconception is that space weather events occur only at solar max. "Impacts from the space environment aren't really correlated with the solar cycle very well. ... What we try to advise our customers is that there are space environment hazards that are there all the time," he said. "Some occur with higher probablility in the years around solar maximum, but nobody really plans their missions around the sunspot number."

In fact, a significant geomagnetic event occurred just a couple of months ago, in April. Was there any impact on satellites? "There may have been," Mazur said. "There's nothing I can tell you in this forum. It was an enhancement of the environment that we haven't seen for a number of years, since December of 2006."

Bottom line? Once again, it pays to be prepared, in 2010 just as much as in 2013.

Stay calm, be prepared. If it does happen, it just might be the impetus for a New Deal. God knows our infrastructure needs it!

The comeing solar max has already been preceeded by the largest solar eruption know, it happened just days ago. Why did many ancient civilizations study and worship the Sun? Why did they base there existance upon it? IMO it is because they knew that the Sun controls all on Earth. IMO the Sun is conrolled by outside forces such as a companion system which shares an orbit around a massive star. This massive star is controlled by a central group of star which are controlled by the Milky Way. Everything in the universe is affected by something else, everything is connected. Of course Aladin would probably beg to differ, hence my continued contraversal posts ( I like to get him going.) I think that everything in the known universe is balanced by cycles which eventually end by merger or death. Of course there are those who believe that everything is chaos based with no purpose or patturns. To each there own. :mrgreen:

thanx toro.is this a recent pic?

also..
nasa has lied to mankind since it's inception,and now im' going to believe them?
i'd believe the national enquirer before nasa.

nasa and the vatican have been the most destructive entities to ever plague mankind.
they have not only set humanity back,they have crippled it.

fuck nasa
and the vatican too

Nasa and the Vatican do not work for the people, they never have. They are organizations that catter to the PTB, and aid in preparations of the elite pigs. We are given the leftovers at best. What we think we know, is only a part of the truth. However it is comeing to the point were the harder we push and search for the truth, the the more :bullshit: these organization will release in order to derail our progress. There tactics will no longer work, and they know it.

i can agree with you on this.
and nowhere in my reply did i say nasa or the vatican 'worked' for the people.
i said they have crippled mankind.

Just trying to understand what you ment, and yes I also believe that we have been crippled. But I also believe that the trueth is comeing out about the two faced organizations. Why else would Obama shut NASA down and say that space travel is going more civilian. I think NASA has been secretly reassigned to other black opp's in order to hide the ultimate purpose of Trillions of dollaes gone missing. :mrgreen:
