Today, NASA's STEREO spacecrafts, A, and B, will be on exactly opposite sides of the sun, and will be taking pictures of its entire surface at the same time. These spacecraft have been travelling round Earth's orbit in opposite directions since October 2006, providing stereo vision of the Sun. Super Sun Day! More at the main site.
Update: and here it is. Cool.
