About the power of yesterday's flare
In response to questions asked, below are some explanations about the power of the event that occurred.
Reliable estimates of the power of yesterday's solar flare are impossible, but there is a possibility that the event is the largest or one of the two largest in the current cycle and falls within the range of X10 - X15. Unfortunately, there is no clear connection between the strength of the plasma ejection and the energy of the flare event. This is because, in addition to the energy of the explosion itself, the Sun's magnetic field also contributes to the acceleration of matter. However, it can also slow down the movement of the plasma cloud. Objective information can only be obtained from direct observations of the explosion site, but in this case, this is impossible. The only spacecraft that could have provided such data, Solar Orbiter, was at a different angle at that moment, from which the explosion area could not be observed.
