On August 31, 2012, a long filament of solar material that had been hovering in the Sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The CME traveled at over 900 miles per second. It did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, with a glancing blow, causing aurora to appear on the night of September 3.
