Submission + - Coronal Mass Ejection Headed for Earth (nasa.gov)

Low Ranked Craig writes: On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was Earth-facing sunspot 1092. Coronal mass ejections (or CMEs) are large clouds of charged particles that are ejected from the Sun over the course of several hours and can carry up to ten billion tons (1016 grams) of plasma. They expand away from the Sun at speeds as high as a million miles an hour. A CME can make the 93-million-mile journey to Earth in just three to four days. When a coronal mass ejection reaches Earth, it interacts with our planet’s magnetic field, potentially creating a geomagnetic storm. The last solar maximum occurred in 2001 and its recent extreme solar minimum was particularly weak and long lasting. These kinds of eruptions are one of the first signs that the Sun is waking up and heading toward another solar maximum expected in the 2013 time frame.

Submission + - Nasa warns of potential 'huge space storm' in 2013 (telegraph.co.uk)

Low Ranked Craig writes: 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. 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. “We know it is coming but we don’t know how bad it is going to be,” said Dr Richard Fisher, the director of Nasa's Heliophysics division. "I believe we're on the threshold of a new era in which space weather can be as influential in our daily lives as ordinary terrestrial weather." Fisher concludes. "We take this very seriously indeed."
