Total solar eclipse, solar prominences. During a solar eclipse, solar prominences are seen just before or after totality. The prominences are large amounts of plasma being ejected from the Sun's surface by turbulence in its magnetic field. A few minutes later, as the Moon completely covers the Sun, the solar corona (a cloud of plasma that surrounds the Sun) will become visible. The moment of totality lasts for only a few minutes. Total solar eclipses usually occur less than once a year, and can only be seen from a small area of the Earth's surface. This total solar eclipse was observed from the USA on 21 August 2017. Totality lasted for just over 2.5 minutes. The time from first contact to last contact was just over 3 hours. Photographed from Idaho. | |
