A spectacular eruption

Earlier today, NASA's Solar Dynamics Observatory (SDO) recorded a spectacular eruption on the sun's northeastern limb. An unstable magnetic filament hundreds of thousands of kilometers long pirouetted and launched a fragment of itself into space. Earth was not in the line of fire, but the SDO movie is worth seeing anyway. Visit  http://spaceweather.com  for cinema.
