Of course, there is
nothing wrong with the sun. It is merely
doing what it has always done. What is
wrong is that in the past century and particularly in the past decade, we chose
to stick our bare behinds out in the way of the occasional blow torch and
everyone knows it will hurt if we catch it.
We actually need to
snug things up under the control of perhaps NORAD in particular and similar
agencies else where. Our sensors will
provide warning that a major EMP blast is on the way and even what time it will
hit. Like a tsunami, very little time is
available to do the right thing, but if one knows what the right thing is and
appropriate drills have been undertaken, it is possible to ride it all out.
Power companies in
particular must go into emergency shutdown.
Public alarms need to be sounded, but the first alarm for most would be
the power going down.
Plenty of damage is
still going to occur, but this way it is constrained to a lot of fried
electronics. The public could even be in
a position to largely ride it out.
The take home now is
that simple cheap methods can hugely control prospective damage. We used them to survive bombs and other
threats, and implementing them is an exercise in education and community
planning.
Ideally the grid can be
brought on line almost immediately and then properly brough up again building
by building.
What's wrong with the sun?
by Terrence Aym
The sun has been worrying scientists for quite
a while.
Back in the late 1990s its eruptions became increasingly violent until it spewed mammoth plasma streamers at an intensity and rate never observed at any other time in history. Earth's satellites were at risk as well as electrical power grids and all electrical communications.
Then the sun went quiet—abnormally quiet. Normal cycles of increased activity came and went with little or no sunspot activity. Around the globe sun watchers began to ask each other—a bit uneasily—what was wrong with the sun?
Their question is about to be answered. The giant is about to awaken from its abnormal slumber and scientists around the world, NASA included, are very concerned.
The director of NASA's Heliophysics Division, Richard Fisher, sheds some light on the growing worry: "The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity. At the same time, our technological society has developed an unprecedented sensitivity to solar storms. The intersection of these two issues is what we're getting together to discuss."
Fisher echoes the growing worry amongst electrical engineers, computer experts, space application experts—even the Pentagon.
The warning shot has been fired
The solar space probe, Solar Dynamics Observatory (SDO) recorded one of the largest solar eruptions in years on April 19, 2010. Experts breathed a collective sigh of relief as the solar storm missed our planet by a wide margin. Some expressed the opinion that we dodged a major bullet.
How long we can continue dodging that bullet is a matter of speculation. The law of averages, however, leads the experts in heliophysics (the study of the properties of the sun) to suspect our days are numbered. The odds of avoiding a planet crippling storm are piling up against Earthlings and our fragile, susceptible technology underlying our civilization. As the sun awakes our risk increases.
Emergency measures to be discussed
At the Space Weather Enterprise Forum being held at the National Press Club on June 8th, some of the world's solar experts are gathering to decide how to protect our technology (and by extension, our civilization) from a rampaging, exploding sun.
Earth's necklace
of orbiting satellites are particularly at risk. The suggestion has been made
to place them in a 'safe-mode' that—theoretically at least—afford them some
protection from the electrified plasma and energized particles of a full blown
solar storm blasting Earth.
Forecasting the intensity, duration and direction of a storm is critical to defending against it.
Forecasting the sun's next move is the business of NOAA's
In that regard, an old NASA satellite, the Advanced Composition Explorer (ACE) launched in 1997, is Bogdan's choice for early warning. "ACE is our best early warning system," asserts Bogdan. "It allows us to notify utility and satellite operators when a storm is about to hit.”
Now into its 4th year, the annual meeting of the Space Weather
As one unnamed observer remarked, the underlying current of the participants this year is one of "frenetic calm."
Back in 2008, the

Fisher worries aloud, "I believe we're on the threshold of a new era in which space weather can be as influential in our daily lives as ordinary terrestrial weather. We take this very seriously indeed."

No need to worry about the sun.
The progressives in the Obama administration will come up with a way to control it if it becomes a real and present danger...
I mean why not? They say they know how to control the climate here on earth & all other problems as well...
Right?
