At the time the data were collected, in late 2008, STEREO-A was nearly 45 degrees ahead of the Earth in its orbit, affording a very clear view of the Earth-Sun line.<br /> <br /> This video is public domain and can be downloaded at: : <a href="http://svs.gsfc.nasa.gov/goto?10809">http://svs.gsfc.nasa.gov/goto?10809</a><br /> <br /> Like our videos?
