Observed by mankind since millenia, solar eclipses impress witnesses. When the eclipse is total, the stars become visible and this is the only time where we can observe the solar corona. Today, their prediction is easy and accurate. In August 1999, a total solar eclipse was visible in Europe. As in all eclipses, from only a small strip of territory it was possible to see the total eclipse.

Here , an animation showing a total eclipse: we are at first dazzled by the Sun (the eclipse is not total) and when the Sun is hidden by the Moon, the corona appears bright around the Sun (the animation is accelerated).
