Scientists have recorded a class C solar flare at an altitude of more than 5,000 kilometers above the Sun’s surface. Flares of this class have virtually no impact on Earth.
The research team investigating the event noticed radio bursts with a repeating signal every 10-20 seconds. The model was “like a heartbeat”. Scientists realized that such events were somehow connected with the breaking and closing of the lines of force of the star’s magnetic field. They have now learned that magnetic islands appear in the expanded electrically conductive layer of the Sun, which are beginning to move rapidly towards the flare region. They repeat every few seconds and release a large number of electrons.
