Three active regions on the sun spotted by the European Space Agency’s (ESA) Proba 2 spacecraft can be seen in this image captured on Wednesday (June 30). ESA’s Space Weather Office said on Twitter the active region 12835 in the lower half of the image has a 24% probability of producing an M class solar flare, the second most powerful type of solar flare. The amount of charged particles that M class solar flares release could cause brief radio blackouts and aurora borealis displays in Earth’s polar regions if they hit the planet. The image was obtained by the Sun Watcher using Active Pixel System detector and Image Processing (SWAP) telescope, which provides images of the sun’s outer atmosphere, the corona, at wavelengths of about 17.4 nanometers. This wavelength corresponds to temperatures of about 1 million degrees Celsius (1.8 million degrees Fahrenheit). The extremely high temperatures of the sun’s corona, several orders of magnitude higher than the temperatures of the sun’s surface, are one of the biggest mysteries in solar physics. — Tereza Pultarova.
