Another solar flare

On April 16, 2012, an M1 class flare was recorded on the Sun, simultaneously with a beautiful prominence appearing on the eastern edge of our Star. These photographs were transmitted to Earth by NASA's solar space observatory — SDO. (Photos SDO | GSFC | NASA).



A prominence (from Latin protubero — I swell) is a dense condensation of material, relatively cooler compared to the solar corona, which rises and is held above the surface of the Sun by magnetic fields. In the photo: prominence on the eastern edge of the Sun on April 16, 2012:

A little about Koronas-Foton. This Russian spacecraft, designed for fundamental research of the Sun, was launched into low Earth orbit from the Plesetsk cosmodrome on January 30, 2009. However, Koronas-Foton did not operate for long. Due to errors in the calculations of the power system, the 'final death' of the satellite was confirmed on April 18, 2010, with a high degree of probability.

The appearance of prominences is often associated with solar flares — an explosive process of energy release in the atmosphere of our Star. The duration of solar flares usually does not exceed a few minutes, and the amount of energy released during this time can reach billions of megatons in TNT equivalent!

And this is what our Sun looked like on April 17, 2012:
