As the magnetic energy in the solar atmosphere is too great, it is suddenly released, which produces a solar flare. The amount of energy released is equivelant to millions of hydrogen bombs exploding at the same time. These solar flares extend out to the layer of the Sun called the corona, or the outermost part of the Sun's atmosphere. The solar wind carries the particles of the solar flare to Earth's magnetosphere which then produces the streaming colors of the aurora borealis.
Inside a solar flare, the temperature is around 15 million degrees Kelvin. The blazing hot loops are located within a strong magnetic field called active regions. These active regions house solar flares and sun spots. When active regions are small and rare and few solar flares are being detected, the solar cycle is at its minimum.
A person cannot view a flare by staring at the Sun, because the flare's emissions are so bright from the photsphere. Scientists use specialized telescopes to observe the Sun's energetic emissions.
