Nasa warns solar flares from ‘huge space storm’ will cause devastation

Solar Maximum is happening now between 2011 and 2013 as part of Solar Cycle 24. My question is, why is this not being reported in the major newspapers and news outlets in the United States?

National power grids could overheat and air travel severely disrupted while electronic items, navigation devices and major satellites could stop working after the Sun reaches its maximum power in a few years.

Senior space agency scientists believe the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013, The Daily Telegraph can disclose.

In a new warning, Nasa said the super storm would hit like “a bolt of lightning” and could cause catastrophic consequences for the world’s health, emergency services and national security unless precautions are taken.

Scientists believe it could damage everything from emergency services’ systems, hospital equipment, banking systems and air traffic control devices, through to “everyday” items such as home computers, iPods and Sat Navs.

Due to humans’ heavy reliance on electronic devices, which are sensitive to magnetic energy, the storm could leave a multi-billion pound damage bill and “potentially devastating” problems for governments.

“We know it is coming but we don’t know how bad it is going to be,” Dr Richard Fisher, the director of Nasa’s Heliophysics division, said in an interview with The Daily Telegraph.

“It will disrupt communication devices such as satellites and car navigations, air travel, the banking system, our computers, everything that is electronic. It will cause major problems for Read more…

Solar Wind to Reach Earth In Few Days, Spark Auroral Activity

A dark coronal hole at the Sun center was captured in extreme ultraviolet light by National Aeronautics and Space Administration’s (NASA) solar dynamics observatory on Jan. 10.

A dark coronoal hole at the Sun center was captured in extreme ultraviolet light by National Aeronautics and Space Administration’s (NASA) solar dynamics observatory. As the Sun continues to rotate, the high speed solar wind particles blowing from this hole will likely reach Earth in a few days and may spark some auroral activity.

Coronal holes are areas of the Sun’s surface that are the source of open magnetic field lines that head way out into space. They are also the source regions of the fast solar wind, which is characterized by a relatively steady speed of about 800 kilometers per second.

As the Sun continues to rotate, the high speed solar wind particles blowing from this hole will likely reach Earth in a few days and may spark some auroral activity, according to NASA.

Here, the solar dynamics observatory detected a giant solar filament that became unstable and erupted from the far side of the Sun. A filament is a large, bright feature extending outward from the Sun’s surface, often in a loop shape. Some filaments break apart and give rise to coronal mass ejections.
