SWAP observes three partial solar eclipses

Three partial solar eclipses were observed  by PROBA-2 as it moved in and out of the Moon’s shadow during the 03-Nov-2013 ‘hybrid’ solar eclipse.

A hybrid eclipse is comprised of a total solar eclipse and an ‘annular eclipse’, depending on an observer’s viewing location on Earth.

During a total solar eclipse, the Moon moves between the Sun and the Earth, their alignment and separation are such that the much closer Moon appears large enough to block out the light from the much more distant Sun.
