  • Proba-2’s partial eclipses

    Proba-2’s partial eclipses

    As the US enjoyed a total solar eclipse on 21 August 2017, ESA’s Sun-watching Proba-2 satellite captured three partial eclipses from its viewpoint, 800 km above Earth. Proba-2 orbits Earth about 14.5 times per day, and thanks to the constant change in viewing angle, it dipped in and out of the Moon’s shadow several times during the solar eclipse.

    The Proba-2 images were taken by the SWAP imager, and show the solar disc in extreme-ultraviolet light to capture its turbulent surface and swirling corona corresponding to temperatures of about a million degrees.

    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.

  • Two solar eclipses for Proba-2

    Two solar eclipses for Proba-2

    As Europe enjoyed a partial solar eclipse on the morning of Friday 20 March 2015, ESA’s Sun-watching Proba-2 minisatellite had a ringside seat from space. Orbiting Earth once approximately every 100 minutes, Proba-2 caught two eclipses over the course of the morning.

    Proba-2 used its SWAP imager to capture the Moon passing in front of the Sun. SWAP views the solar disc at extreme ultraviolet wavelengths to capture the turbulent surface of the Sun and its swirling corona.
