The sun may finally come to life from its slumber. On May 29, the sun erupted its strongest flare since October 2017, an eruption observed by NASA at the Solar Dynamics Observatory (SDO). Solar flares come from radiation bursts of sunspots, and temporary darkness and relatively cool patches on the sun’s surface have a very strong magnetic field.
Scientists have divided strong flares into three categories: C, M and X. Each category is 10 times more powerful than its next level. The M flare is 10 times stronger than the C flare, but 10 times weaker than the Class X event.
It is important to note that the impact of solar flare eruptions on the Earth is huge and harmful. It is one of the most intense solar activity. The sun’s surface suddenly appears bright spots shining, only between a few minutes and a few dozen minutes, the brightness rises rapidly, and then slowly weakens.
Once a solar flare occurs, it is a earth-shaking explosion on the surface of the sun. Solar flares release the equivalent of 100,000 to 1 million strong volcanic eruptions, bai or the explosion of tens of billions of 100-ton hydrogen bombs, and a large flare burst that releases huge amounts of energy in a quarter of a minute or twenty minutes.
At present, scientists’ predictions of solar flare sepsis are limited, according to U.S. scientists, solar flareeruptions will not only seriously endanger the safety of astronauts and instruments in the spacecraft, radio communications, especially short-wave communications, as well as television and radio broadcasts, will also be disturbed or even interrupted, solar flares occur when the aurora, and interfere with the Earth’s magnetic field caused magnetic storms.
In addition, solar flares also have different degrees of direct or indirect influence on meteorology, hydrology and the growth of plants and animals.
Today’s flare sepsis is M-class, so don’t panic too much, and it’s not aimed at the Earth.
NASA officials say the flare may have erupted because the sun is gradually rising to its active phase. The activity period is 11 years. If so, the most recent cycle, known as solar cycle 24, may now be over.
Scientists define the beginning of a new cycle as “the sun’s minimum”, i.e. the sun has the least number of sunspots and the least active time.
“It will take at least six months of solar observation and sunspot count to know when it will occur,” NASA officials wrote today in a new report announcing the SDO flare detection. “
NASA officials added: “Because the minimum value is determined by the lowest number of blacks in a cycle, scientists need to observe an increasing number before they can determine when they are at their lowest level.” “
“This means that the sun’s minimum can only be identified after the fact: it can take six to 12 months to determine when the minimum value is actually passed.” “
