What Happens When Giant CME Slams Earth’s Magnetic Field, Sun Spits Out An Earth Directed Coronal Mass Ejection
The Solar and Heliospheric Observatory (SOHO) captured this image of the sun at 5:06 a.m. EDT on Oct 5, 2012 showing a coronal mass ejection (CME) spreading away from the sun toward Earth.
At 11:24 p.m. EDT on Oct. 4, 2012, the sun unleashed a coronal mass ejection (CME). Not to be confused with a solar flare, which is a burst of light and radiation, CMEs are a phenomenon that can send solar particles into space and can reach Earth one to three days later. Experimental NASA research models show the CME to be traveling at about 400 miles per second.
When Earth-directed, CMEs can affect electronic systems in satellites and on Earth. CMEs of this speed, however, have not generally caused major effects in the past. Further updates will be provided if needed.
NOAA’s Space Weather Prediction Center (http://swpc.noaa.gov) is the United States Government official source for space weather forecasts.
A giant explosion of magnetic energy from the sun, called a coronal mass ejection, slams into and is deflected completely by the Earth’s powerful magnetic field. The sun also continually sends out streams of light and radiation energy.
Much of the radiation energy that makes it through is reflected back into space by clouds, ice and snow and the energy that remains helps to drive the Earth system, powering a remarkable planetary engine – the climate. It becomes the energy that feeds swirling wind and ocean currents as cold air and surface waters move toward the equator and warm air and water moves toward the poles – all in an attempt to equalize temperatures around the world.

Whoever commands how the Sun will act likewise holds the fate of mankind in his hands.
That person is neither Romney or Obama.
The graphics make it look extra scary. How about telling us when it is supposed to hit? 1 to 3 days seems rather imprecise for NOAA.
god bless earthlings
and if the notion of TIME disappears…big trouble or just PEACE in the mind …of the CREATOR of you!
It was Mitt Romney’s toilet seat sent flying out of an American Airline plane.
No one controls the sun……. To even put the 2 president elects in that sentence shows you need to go back to solar class 101 and learn some about how stars actually work. Not your famous Hollywood stars but true stars.
As to when it will hit the times are imprecise because it varies due to several variables. Speed, particle mass, the solar winds pushing it and the event itself.
To see its data a good basic site that gives a compileation of most other sites is http://www.solarham.net/ to get videos of the event or even previous ones go to the source http://sohodata.nascom.nasa.gov/cgi-bin/soho_movie_theater just pop in the dates and let the pictures load and watch it unfold.
Even if it is not earth pointing at the time of event the solar winds will spin it into our path sometimes here is a prediction model of the last while
