17 powerful flares recorded on the Sun in two days

It is noted that the plasma ejected during the flares will reach the Earth on the evening of May 25 and provoke a moderate

magnetic storm. This could disrupt the operation of satellites in orbit, interfere with radio communication systems on Earth, and also threaten the health of astronauts.

Among the flares there were three M-class events. M-class solar flares are the average of the large flares. They cause low (R1) to moderate (R2) levels of radio interference on the dayside of the Earth.

Despite the rather long duration,the amplitude of magnetic storms is expected to be insignificant — it will not exceed level 2 on a 5-point scale. This is due to the fact that the strength of solar flares is far from record values. In addition, the direction of the coronal mass ejection was slightly shifted from the direction towards the Earth, which will significantly soften the force of the impact. 

Observatory message

It is noted that the level of flare activity on the Sun constantly rises and falls with a periodicity of approximately 11 years. However, this pattern began to break down. 

Many theorists suggest that such anomalies indicate fundamental changes in the work of the sun's interior, but the authors are inclined in favor of the fact that the cycle is gradually returning to normal.
