Our star, the sun, is 4,57 billion years old and belongs to the spectral class G2V yellow-orange. She is a so-called yellow dwarf at best age compared to other stars. We will still be approx. Another 4,5 billion years can enjoy her. However, their end will also be our end...
The shot shows the AR2765 sunspot and a protuberance, an ejection of hot gas, on the surface.

An airplane flies in front of the solar disk while the Sun begins to awaken its activity with AR 2757 in the center; a small sunspot, small in apparent size but as large as Earth.

To take this picture, the summer season is expected and the sunset and takeoff of the planes are calculated (every 10 minutes).
