ESA Science & Technology - A composite image of SOHO and ground-based views of the solar eclipse

With a unique view from the first Lagrangian point (L1), outside the disturbing influence of Earth's atmosphere, SOHO's Large Angle Spectrometric Coronagraph (LASCO) produces its own eclipse all the time by simply blocking direct light from the solar disk. Other instruments on board look directly at the Sun, with the same advantage of an uninterrupted view - there are no nights on SOHO, and the Moon never gets in the way. So, when a total eclipse happens to be observable from Earth, SOHO is one of the primary sources of information about what lies in wait for the eager observers in possibly remote locations.
