The history of the solar storm


A geomagnetic storm turn off the electricity grid in most of Quebec,in march 1989.At that time,  millions of Canadians was leaving without power for hours.In March 1989,The NASA reports,in January 1994 the communications satellite 290 million Anik E2   Canada, was shat down by a solar storm, and took six  months and $ 50-70 million put back into operation.One of the most dangerous contributors to solar storms is a coronal mass ejection (CME), a great cloud of charged particles belched from the sun and sailing through space at supersonic speeds.

Storms are classified in various intensities


The Solar Wind, which had an average speed of 500 km / sec, reached in the three days following a speed of more than 50,000 km / sec. From there began to descend to 33,000 km / sec, speed was maintained for 30 days. Although this seemed impossible, what happened?
The event was mentioned in all the magazines in the world, and in major newspapers, but scientists did not know what it was. All they did was to publish the data at their disposal. In 1989, a class X19 solar flare, issued a radioactive storm hit Earth and knocked out the Hydro-Quebec power grid for several hours, to merge several generators.

The Sun Satellites by Observing


Astronomers still have no idea why they occur in more or less regular cycles of 11 years. There is, however, a broad scientific consensus that the entire solar activity, which essentially consists of various forms of explosions and bursts of sun-grown when the number of sunspots, and decreases when this number decreases.
Most of the explosions of sunspots belong to a common variety known as Coronal Mass Ejection (CME). CMEs are clouds of gas at high temperatures leaving the Sun and Interplanetary Space cross, creating shock waves that accelerate different particles, mostly protons, in front of them and resulting in what is known as Proton Storm.
