NASA's Earth Observatory Shows Solar Flare

staaktdenarbeid writes "In the past few months I became very impressed with the timeliness and quality of NASA's Earth Observatory. When hurricane Isabel struck, their imagery showed me the biggest latte ever made. Now that Southern California is on fire, it takes only a look from outer space to see how bad the sitation really is. And, today, a massive solar flare showed up on their website as soon as it errupted (so to speak). Each of these pictures is accompanied by detailed technical background. And for the rest of us, they also make perfect screen backgrounds. Very cool."

Certainly, it's not a massive hole like down at the South Pole, but it's definitely noticeable at these latitudes.
