UFA, 7 September 2017. /Bashinform News Agency, Galiya Nabieva/. The solar flare, which occurred on Wednesday, has become the largest in the last 12 years, according to a report by the Laboratory of X-ray Solar Astronomy at the Lebedev Physical Institute of the Russian Academy of Sciences (FIAN). The September 6th flash was awarded a score of X9.3 - the last outburst of such force was observed on September 7, 2005, TASS reported. According to experts, they still have to understand how such a powerful flare could occur against the background of a minimum solar activity.

This value is already outside the usual color scale, which consists of five values (from green to yellow, orange, red and maximum, violet, activity levels of the Sun) and corresponds to the so-called black, higher activity level.
