The annular solar eclipse on 29 April was seen as a dark shadow on the edge of Meteosat-7's view.
This was the first solar eclipse of 2014. Solar eclipses occur when the Moon passes between Earth and the Sun. Total eclipses happen when the Moon is closer to earth and precisely covers the sun — creating a 'diamond ring' effect when seen from Earth. An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. — creating a 'ring of fire' or annulus around the Moon's silhouette.
On our satellite imagery eclipses are seen as dark shadows or anomalies. In the animation the dark shadow can be seen crossing near the edge of Antarctica, just after dawn.
