But that still can change as the storm shakes the planet’s magnetic field in ways that could disrupt technology but also spread colorful Northern Lights. Early indications show that it is about 10 times stronger than the normal solar wind that hits Earth.

The storm started with a massive solar flare Tuesday evening and grew as it raced outward from the sun, expanding like a giant soap bubble, scientists said. The charged particles were expected to hit at 4 million mph (6.4 million kph).

The storm struck about 6 a.m. EST (1100 GMT) in a direction that causes the least amount of problems, said Joe Kunches, a scientist at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.

“It’s not a terribly strong event. It’s a very interesting event,” he said.

Forecasters can predict the speed a solar storm travels and its strength, but the north-south orientation is the wild card. And this time, Earth got dealt a good card with a northern orientation, which is “pretty benign,” Kunches said. If it had been southern, that would have caused the most damaging technological disruption and biggest auroras.

“We’re not out of the woods,” Kunches said Thursday morning. “It was a good start. If I’m a power grid, I’m really happy so far.”

But that storm orientation can and is changing, he said.

“It could flip-flop and we could end up with the strength of the storm still to come,” Kunches said from the NOAA forecast center.

North American utilities so far have not reported any problems, said Kimberly Mielcarek, spokeswoman for the North American Electric Reliability Corporation, a consortium of electricity grid operators

A massive cloud of charged particles can disrupt utility grids, airline flights, satellite networks and glovbal positioning services, especially in northern areas. But the same blast can also paint colorful auroras farther from the poles than normal.

Astronomers say the sun has been relatively quiet for some time. And this storm, while strong, may seem fiercer because Earth has been lulled by several years of weak solar activity.

The storm is part of the sun’s normal 11-year cycle, which is supposed to reach a peak next year. Solar storms do not harm people, but they do disrupt technology. And during the last peak around 2002, experts learned that GPS was vulnerable to solar outbursts.

Because new technology has flourished since then, scientists could discover that some new systems are also at risk, said Jeffrey Hughes, director of the Center for Integrated Space Weather Modeling at Boston University.

The region of the sun that erupted can still send more blasts our way, Kunches said. Another set of active sunspots is ready to aim at Earth.

“This is a big sun spot group, particularly nasty,” NASA solar physicist David Hathaway said. “Things are really twisted up and mixed up. It keeps flaring.”

Storms like this start with sun spots, Hathaway said.

Then comes an initial solar flare of subatomic particles that resemble a filament coming out of the sun. That part from this storm hit Earth only minutes after the initial burst, bringing radio and radiation disturbances.

After that comes the coronal mass ejection, which looks like a growing bubble and takes a couple days to reach Earth.

The Astronomical Society in Jeddah confirmed a super solar storm will hit the Earth at the end of 2012 or the beginning of 2013. The greatest impact of this storm will be on the communications sector.

"It is expected at the beginning of the new solar circle, which represents an increase in sunspots on the sun's surface. The sunspots usually have tremendous activity resulting from the interactions of sunspots with each other. These interactions generate a solar explosion that releases a massive storm into space. The storm will be earth-bound and will hit the earth's magnetic field. It generates either the phenomenon of 'Aurora Borealis' or the so-called 'North damage.' This phenomenon can penetrate the radio waves. However, it all depends on the force of the solar explosion," Majed Abu Zahra, president of The Astronomical Society in Jeddah, told Arab News.

"The consequences of this storm will affect the telecommunications, technical and electricity sectors. In March 1989, when the sun was at the top of its activity it launched streams of massive X-ray, and ultraviolet radiation reached the upper layer of the earth's atmosphere with charged positive protons and negative electrons that led to heating of the upper layer and expanding it into the external space, affecting satellites moving in low orbits," said Abu Zahra.

"The phenomenon of ‘Aurora Borealis’ can result in a temporary interruption of the wireless communication (radio waves). However, this phenomenon has no direct effect on the human life as the Earth is surrounded by the atmosphere and magnetic fields, but the real danger is to astronauts outside the Earth's atmosphere if they do not take the necessary safety precautions," added Abu Zahra.

The society’s website is updating its warning that there may be super solar storms hitting the earth and may disrupt electronic devices.

"The food trucks will no longer be able to supply stores with food. The cell phones and computers also will no longer work. Without power from the grid most factories will no longer work. Within three days or so, food that's in your local store will be gone. Since most cars and trucks today require electronic ignition to work, most vehicles will likely not work. However non-electric trains most likely would continue to work," according to the website.

"There are suggested mechanisms by which solar variations may have an effect on climate. The first is solar irradiance changes directly affecting the climate. This is generally considered to be a minor effect, as the amplitudes of the variations in solar irradiance are much too small to have a significant effect. Secondly, there are variations in the ultraviolet component. The UV component varies by more than the total, so if UV were for some (as yet unknown) reason having a disproportionate effect, this might explain a larger solar signal in climate," Dr. Zaki Al-Mustafa, president of the Astronomy department in King Abdul Aziz City for Science and Technology (KACST) told Arab News.

However, the fears of the solar storm's negative impact on the commercial sectors might push insurance companies to increase security according to the size of risk. At the same time, insurance companies name such phenomena as "acts of God" which means it is outside insurance coverage, according to industry experts.

"The insurance companies do not cover climate change losses. However, the aviation sector is already insured by the insurance companies. If there is a possibility of a huge risk, the insurance companies will increase the security guards' value," Ibrahim Youssef Al-Ramel, former member of the insurance committee of Jeddah Chamber of Commerce and Industry told Arab News.

The aviation sector will be the biggest loser due to the solar storm’s negative impact on the communications sector. However, there are many commercial sectors that will also be affected. Estimated losses may reach more than $1 billion, according to economic experts.

"The governments usually play a big role to compensate the losses resulting from climate changes as insurance companies cannot compensate these losses. However, no one can estimate the value of losses," Yaseen Al- Jeffri, economic analyst, told Arab News.
