"NASA’s solar shield
The good news for Larry Rodriguez is that if the solar Katrina does occur, at least he’ll have between one and four days notice. NASA has put in place a defence called ‘solar shield’ consisting of satellites that can spot solar storms destined for earth. Although it identifies them days in advance, the crucial moment comes about 30 minutes before impact when the storm sweeps past ACE, a spacecraft stationed roughly a million miles from earth.
The craft measures the storm’s speed, density, and magnetic field and transmits the data to Earth where scientists say they can work out where exactly damage will be greatest, allowing them to warn public utilities."
