Huge solar storm may hit earth today, Friday the 13th
If your mobile networks are affected today, Friday the 13th, blame it on solar flares. Three extremely powerful solar flares that the sun has emitted could send shockwaves through earth on Friday, scientists fear, news.com.au reports. The solar flares may disrupt the communication lines, causing blackouts. The three solar flares were all 'X-class' flares, which are almost 10,000 times as powerful as normal background flares from the sun.
Solar flares, according to Live Science, are 'powerful bursts of radiation that are unleashed from the sun and speed out into space. They can sometimes produce waves of plasma and charged particles, called coronal mass ejections (CMEs). When aimed directly at Earth, CMEs can trigger geomagnetic storms and knock out communications and power grids on Earth.'

his image combines two sets of observations of the sun at 10:45 AM EDT, July 12, 2012 from the Solar Dynamics Observatory (SDO) to give an impression of what the sun looked like shortly before it unleashed an X-class flare beginning at 12:11 PM EDT. The image incorporates light in the 171 Angstrom wavelength, which shows off giant loops of solar material overlying the middle of the sun over Active Region 1520 where the flare originated. The second set of observations is called a magnetogram, which highlights magnetic fields on the sun. Together these kinds of observations can help scientists understand the magnetic properties of the sun that lead to giant explosions like flares. less
