Proba-2 partial eclipses


ESA’s Earth-orbiting Proba-2 satellite observed three partial solar eclipses on the morning of 13 September 2015 along with an additional passage of the Moon close to the edge of the Sun. The image was taken with Proba-2’s SWAP imager, which views the solar disc at extreme ultraviolet wavelengths to capture the turbulent surface of the Sun and its swirling corona, which can clearly be seen in between eclipses in this movie. The Sun’s rotation can also be seen.

  1. most people are used to seeing time-lapses of solar activity taken over several days. Here, it was all recorded in less than five hours, which is why the sun appears so slow and inactive compared to what we are used to see.
