Sunspot Tosses Plasma Cloud Toward Earth

parallel_prankster writes "The Washington Post reports that a huge sunspot unleashed a blob of charged plasma Thursday that space weather watchers predict will blast past the Earth on Sunday. Satellite operators and power companies are keeping a close eye on the incoming cloud, which could distort the Earth's magnetic field and disrupt radio communications, especially at higher latitudes. The huge blob of charged gas spotted by NASA satellites is speeding toward Earth at more than 2 million mph. The most damaging solar discharges, which are very rare, can move at speeds more than twice that fast. Here's a more detailed article with some animation."
