Sunspot Tosses Plasma Cloud Toward Earth 94
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."

Besides sparking pretty auroras, heightened solar activity has a more tangible benefit: It cleans up space junk. As the sun acts up, the Earth’s atmosphere expands, increasing friction on dead satellites, rocket parts and other trash in low Earth orbit, pulling them down.
The amount of debris in Earth orbit “actually decreased during 2011 as solar activity increased toward an anticipated maximum,” NASA’s chief space junk watcher, Nicholas Johnson, wrote in the January issue of the agency’s Orbital Debris Quarterly Newsletter.
