Solar Fares For Beginners

Sometimes a sudden, rapid, and intense variation in brightness is seen on the Sun. That is a solar flare. A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. On the Sun's surface are huge magnetic loops called prominences. When they touch, they short circuit each other, setting off explosions. The amount of energy released is the equivalent of millions of 100-megaton hydrogen bombs exploding at the same time! A solar flare contains high energy photons and particles, and is released from the Sun in a relatively short amount of time (a few minutes).

When the Grid Goes Down, You Better Be Ready!

This is a very interesting article on the grid instability by Tess Pennington

When the Grid Goes Down, You Better Be Ready!
by Tess Pennington

It is a fact that our country is more reliant on electrical power today than at any time in its history. Our way of life – from everyday conveniences and the security of local emergency services to commerce and communications – is contingent upon an always on, always available flow of electricity. But an aging infrastructure coupled with a rise in natural and man-made disasters threatens our entire modern day digital infrastructure. According to many experts from the private and public sector, we’re just one major catastrophic event away from a complete meltdown of life in America as we know it today.

So, what happens if and when the grid goes down for an extended period of time? Aside from the aggravation of not being able to determine what is happening through traditional media channels, for the Average Joe, his problems have only just begun. Our dependency to the grid doesn’t just stop at lack of electricity in our homes to power our appliances or an inability to charge our cell phones; it is much broader and affects every aspect of our lives.

We are regularly inundated with news reports covering outages that last several days or weeks resulting from inclement weather like snow storms or hurricanes, or heat waves in southern states that threaten to overload the system. During those times, when entire metropolitan areas or regions experience black outs, we get a glimpse into what a truly widespread emergency might look like. It is often the case that the first thing residents of affected areas do is rush to grocery and hardware stores hoping to acquire critical supplies like food, water, batteries, flashlights and generators. And while these supplies acquired at the onset of crisis may provide short term sustenance, any long-term grid-down situation that lasts for many weeks or months will prove dangerous, and perhaps fatal, to the unprepared.

Consider, for a moment, how drastically your life would change without the continuous flow of energy the grid delivers. While manageable during a short-term disaster, losing access to the following critical elements of our just-in-time society would wreak havoc on the system.

  • Challenges or shut downs of business commerce
  • Breakdown of our basic infrastructure: communications, mass transportation, supply chains
  • Inability to access money via atm machines
  • Payroll service interruptions
  • Interruptions in public facilities – schools, workplaces may close, and public gatherings.
  • Inability to have access to clean drinking water

Neil Swidey, in his article What If The Lights Go Out?, indicates that the grid may be ill-equipped to meet all the enormous challenges it faces in this day and age.

The last widespread outage in the Northeast, the great blackout of August 2003, showed how intimately interconnected and alarmingly fragile our power grid is. How else to explain the way a problem starting in northeastern Ohio quickly cascaded into a blackout affecting 50 million people across the northeastern United States and parts of Canada? How quickly? Between the moment a power surge came rushing out of Ohio and the moment Manhattan began to go dark, exactly 10 seconds had passed.

..

If our society is more reliant on power than at any time in history – without it, we’ve got no commerce, no communications, no clean water – and if power becomes less reliable in the future, the big question is: Will we be able to hack it?

..

THE TROUBLE with the future of power isn’t that there is one big problem that could croak us. It’s that there are a host of them, any one of which could croak us.

Neil Swidey has grouped these potential grid-down antagonizers into three categories:

1. Extreme Natural Disasters

This includes earthquakes, hurricanes, snow storms, thunderstorms as well as massive solar storms that have the potential to seriously damage the electrical grid. You don’t think it could happen? In the article provided above, the author states, “It took just 90 seconds for a 1989 solar storm to cause the collapse of the Hydro-Quebec power grid, leaving 6 million Canadians without power for up to nine hours. A 2008 NASA-funded report noted the risk of significant damage to our interconnected grid in light of the forecast for increased solar activity. The 11-year solar cycle is expected to peak in 2013, and just two weeks ago we saw one of the biggest solar-radiation storms in years.

2. Acts of Terrorists

This category includes, but is not limited to a physical attack on the bulk power system, either at its source of generation or somewhere along its transmission route, cyber attack on the computers controlling our interconnected grid, electro-magnetic pulse, or EMP, weapon. Have you read One Second After by William R. Forstchen? EMP’s will create long-lasting damage that would incapacitate electronic systems across the country and forever change our way of life. Cyber-threats are another concern and someone with serious hacking skills could easily take out computers, networks or information stored therein to cause lasting damage to our way of life.

3. The Ailing Grid

Our ailing power grid is almost as sick as our failing economy. With one malicious event, be it man made or by natural means, it is down. Swidey compares the grid infrastructure to being as old and stooped as a pensioner. As it is upgraded and its capacity is expanded, our rapacious need for more electrical power races to max it out once again.

A wide-spread emergency, such as a massive power surge, solar flare or rogue electromagnetic pulse (EMP) detonation have the capacity to render our entire power infrastructure useless. Transformers and other key elements on which the grid depends could be permanently damaged as a result of massive electric surges.

In an event such as this our immediate problem will be finding a way to order, manufacture and take delivery of the components needed to replace the faulty ones. Most of the parts made for our electrical grid are made in China – and many are decades old. According to Congressman Roscoe Bartlett, who recently warned people to get their families out of major cities because of concerns about the stability of the grid, it would take months to get the parts shipped to this country and replaced.

During the outage, millions would be adversely affected, with some like Frank Gaffney, president of the Center for Security Policy, suggesting that within a year 9 out of 10 Americans would be dead from starvation, disease and violence.

Ladies and gentleman, if there’s one thing that can cause the veritable “S” to hit the fan, this is it.

So how do we remedy and/or prepare for a grid down scenario? Think retro – like pioneer retro- and by that we have to go way back to when we were not so dependent on the luxury of on-demand energy in its various forms. When preparing for a grid-down scenario, we must comprise different contingency plans for short-term and longer-term issues. That being the case, we have to admit to ourselves that it could last longer than we expect and much more than just a minor inconvenience. Therefore, the best way to prepare is to start with your basic needs. That is the need for light, heat, water, and food. Some preparedness items to stock up on are:

  • Alternative fuel sources such as solar and diesel, wood for burning.
  • Food preservation supplies – dehydrators, canners, smokers, fermenting/pickling supplies. To learn more, click here.
  • Bulk food – Canned, freeze-dried, dehydrated or dry goods.
  • Water filtration supplies, rain harvesting supplies and large quantities of stored water.
  • Light sources: Lanterns, flashlights, candles and matches and alternative light sources
  • Batteries and chargers
  • Emergency stove – solar oven, rocket stove, camping stoves, etc.
  • Wood burning fire place – Central air heating systems, even if they use natural gas or propane, depend on electricity for the blower that will circulate the heated air. When the grid is down, this system will not work. Having a wood burning fire place is an alternative to central heating systems.
  • Cash money and/or silver or gold currency.

The vulnerability of our grid is nothing new to preppers. Some have seen this problem coming for a long time and changed their entire ways of life by going off-grid. They have found alternative sources such as solar, wind and diesel to power their homes and machinery. A majority of us, who have not gone off-grid, are making a concerted effort to avoid dependence on this ailing infrastructure and preparing for life without it. That being said, all we can do is stay the course, prepare accordingly and continue on.

NASA Explains What Would Happen if the 1921 Solar Flare Hit Today

This an excerpt from a 132-page NASA funded report titled Severe Space Weather Event - Understanding Societal and Economic Impacts, suggests that the right magnitude storm could be devastating:

The problem begins with the electric power grid. “Electric power is modern society’s cornerstone technology on which virtually all other infrastructures and services depend,” the report notes. Yet it is particularly vulnerable to bad space weather. Ground currents induced during geomagnetic storms can actually melt the copper windings of transformers at the heart of many power distribution systems. Sprawling power lines act like antennas, picking up the currents and spreading the problem over a wide area. The most famous geomagnetic power outage happened during a space storm in March 1989 when six million people in Quebec lost power for 9 hours.

According to the report, power grids may be more vulnerable than ever. The problem is interconnectedness. In recent years, utilities have joined grids together to allow long-distance transmission of low-cost power to areas of sudden demand. On a hot summer day in California, for instance, people in Los Angeles might be running their air conditioners on power routed from Oregon. It makes economic sense,”but not necessarily geomagnetic sense. Interconnectedness makes the system susceptible to wide-ranging “cascade failures.”

To estimate the scale of such a failure, report co-author John Kappenmann of the Metatech Corporation looked at the great geomagnetic storm of May 1921, which produced ground currents as much as ten times stronger than the 1989 Quebec storm, and modeled its effect on the modern power grid. He found more than 350 transformers at risk of permanent damage and 130 million people without power. The loss of electricity would ripple across the social infrastructure with “water distribution affected within several hours; perishable foods and medications lost in 12-24 hours; loss of heating/air conditioning, sewage disposal, phone service, fuel re-supply and so on.

“The concept of interdependency,” the report notes, “is evident in the unavailability of water due to long-term outage of electric power–and the inability to restart an electric generator without water on site.”

What if the May 1921 superstorm occurred today? A US map of vulnerable transformers with areas of probable system collapse encircled. A state-by-state map of transformer vulnerability is also available: click here.

The potential for major disruptions to our lives and our modern day just-in-time delivery systems could lead to total chaos in affected areas:

“A contemporary repetition of the Carrington Event would cause an extensive social and economic disruptions,” the report warns. Power outages would be accompanied by radio blackouts and satellite malfunctions; telecommunications, GPS navigation, banking and finance, and transportation would all be affected. Some problems would correct themselves with the fading of the storm: radio and GPS transmissions could come back online fairly quickly. Other problems would be lasting: a burnt-out multi-ton transformer, for instance, can take weeks or months to repair. The total economic impact in the first year alone could reach $2 trillion, some 20 times greater than the costs of a Hurricane Katrina or, to use a timelier example, a few TARP

Solar Flare Effects on the Grid

Newly discovered evidence by NASA predicts that a super solar storm coming in mid-May 2012, which occurred on Earth in 1805, could occur again and knock out all electricity on the planet, taking us back 100 years.

Prior to 2006, researchers at NASA and other similar think-tanks discovered strong evidence that a solar storm is coming–and this week the most intense solar maximum in fifty years has been detected. The facts are starting to grow.

The prediction has been issued by a team led by Mausumi Dikpati of the National Center for Atmospheric Research (NCAR). Dikpati’s prediction is unprecedented.

According to Dikpati “The next sunspot cycle will be 30% to 50% stronger than the previous one,” she says. If correct, the next solar maximum forecast for 2012 would be a global catastrophe–second only to the historic Solar Max of 1958 and 1805."

However, in 1958 and 1805 humans didn’t rely as much on technology as we do now. The entire economy and communications network of the world is dependent on these technologies–in a nutshell a solar flair would cripple us.

NASA''s Concerns over the Solar Minimums

This is an excerpt from NASA's site: NASA Science News: http://science.nasa.gov/science-news/science-at-nasa/2009/01apr_deepsolarminimum/

Deep Solar Minimum

April 1, 2009: The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower.

2008 was a bear. There were no sunspots observed on 266 of the year's 366 days (73%). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days: plot. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008.

Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year's 90 days (87%).

It adds up to one inescapable conclusion: "We're experiencing a very deep solar minimum," says solar physicist Dean Pesnell of the Goddard Space Flight Center.

"This is the quietest sun we've seen in almost a century," agrees sunspot expert David Hathaway of the Marshall Space Flight Center.

Quiet suns come along every 11 years or so. It's a natural part of the sunspot cycle, discovered by German astronomer Heinrich Schwabe in the mid-1800s. Sunspots are planet-sized islands of magnetism on the surface of the sun; they are sources of solar flares, coronal mass ejections and intense UV radiation. Plotting sunspot counts, Schwabe saw that peaks of solar activity were always followed by valleys of relative calm—a clockwork pattern that has held true for more than 200 years: plot.

The current solar minimum is part of that pattern. In fact, it's right on time. "We're due for a bit of quiet—and here it is," says Pesnell.



But is it supposed to be this quiet? In 2008, the sun set the following records:

A 50-year low in solar wind pressure: Measurements by the Ulysses spacecraft reveal a 20% drop in solar wind pressure since the mid-1990s—the lowest point since such measurements began in the 1960s. The solar wind helps keep galactic cosmic rays out of the inner solar system. With the solar wind flagging, more cosmic rays are permitted to enter, resulting in increased health hazards for astronauts. Weaker solar wind also means fewer geomagnetic storms and auroras on Earth.

A 12-year low in solar "irradiance": Careful measurements by several NASA spacecraft show that the sun's brightness has dropped by 0.02% at visible wavelengths and 6% at extreme UV wavelengths since the solar minimum of 1996. The changes so far are not enough to reverse the course of global warming, but there are some other significant side-effects: Earth's upper atmosphere is heated less by the sun and it is therefore less "puffed up." Satellites in low Earth orbit experience less atmospheric drag, extending their operational lifetimes. Unfortunately, space junk also remains longer in Earth orbit, increasing hazards to spacecraft and satellites.

Above: Space-age measurements of the total solar irradiance (brightness summed across all wavelengths). This plot, which comes from researcher C. Fröhlich, was shown by Dean Pesnell at the Fall 2008 AGU meeting during a lecture entitled "What is Solar Minimum and Why Should We Care?"

A 55-year low in solar radio emissions: After World War II, astronomers began keeping records of the sun's brightness at radio wavelengths. Records of 10.7 cm flux extend back all the way to the early 1950s. Radio telescopes are now recording the dimmest "radio sun" since 1955: plot. Some researchers believe that the lessening of radio emissions is an indication of weakness in the sun's global magnetic field. No one is certain, however, because the source of these long-monitored radio emissions is not fully understood.

All these lows have sparked a debate about whether the ongoing minimum is "weird", "extreme" or just an overdue "market correction" following a string of unusually intense solar maxima.

"Since the Space Age began in the 1950s, solar activity has been generally high," notes Hathaway. "Five of the ten most intense solar cycles on record have occurred in the last 50 years. We're just not used to this kind of deep calm."

Deep calm was fairly common a hundred years ago. The solar minima of 1901 and 1913, for instance, were even longer than the one we're experiencing now. To match those minima in terms of depth and longevity, the current minimum will have to last at least another year.

see captionIn a way, the calm is exciting, says Pesnell. "For the first time in history, we're getting to see what a deep solar minimum is really like." A fleet of spacecraft including the Solar and Heliospheric Observatory (SOHO), the twin STEREO probes, the five THEMIS probes, Hinode, ACE, Wind, TRACE, AIM, TIMED, Geotail and others are studying the sun and its effects on Earth 24/7 using technology that didn't exist 100 years ago. Their measurements of solar wind, cosmic rays, irradiance and magnetic fields show that solar minimum is much more interesting and profound than anyone expected.

Solar Minimum

Solar Maximum

The solar storm works in approximately an 11 year cycle. There is solar minimum (the least amount of solar storm) and solar maximum (the greatest amount). The last solar maximum was in 2001 and the last solar minimums was in 2006. The next solar max is predicted for 2012.

Solar Maximum 2012

An article was published on NASA’s website in 2006 (during the last solar minimum) titled Solar Storm Warning . This article by Science@NASA’s Dr. Tony Philips explains that the 2012 solar max will be the greatest since 1958 (when the Northern Lights were visible in Mexico).

“The next sunspot cycle will be 30% to 50% stronger than the previous one.” Mausumi Dikpati of the National Center for Atmospheric Research (NCAR)
