mariana3 says: Spaceweather says: "...Last night a gust of solar wind sent auroras rippling down from Canada into the United States. Shawn Malone sends this picture from Marquette, Michigan... "There was a nice burst of aurora activity right after sunset," says Malone who captured the scene using his Canon 5D. "The thawing snowbanks in the foreground were not the most scenic, but I had to act quickly to catch the auroras." The solar wind continues to blow and more geomagnetic storms are possible tonight. Northern (and not-so-northern) sky watchers should be alert for auroras." Just so gorgeous! As the poles shift these will be common in even lower latitudes As the poles shift? The magnetic pole reversal that is starting. Happens every 250,000 years or so. Last one was about 700,000 years ago so we are due anyway. Its a normal process of our planet. http://www.pbs.org/wgbh/nova/magnetic/ This is pretty old news, now. As this time line shows, our planet's magnetic shield has reversed its direction hundreds of times. |
