More solar eclipse stuff

As a day or so has passed, more pictures and the like are coming in from the events of the 11th of July solar eclipse. has a gallery. Meanwhile above the Earth, the Proba-2 satellite took measurements during the eclipse, looking at how different wavelengths of light are extinguished and also how the overall illumination of the solar disc changes during the eclipse. The Sun is partly translucent and so its illumination isn’t uniform across the disc. This kind of measurement of limb darkening and other effects is useful in cases of other objects transiting stars, like exoplanets.
