February** Dynamic Incentive Program
On the afternoon of February 16th, an x2. erupted in the active zone on the west side of the SunLevel 5 Great Flare, is this level high?
The intensity of a flare also has a corresponding numerical level, which is generally measured by the peak flux of X-rays, measured in watts square meters, from low to high, A, B, C, M (large flare) and X (very large flare), in which the intensity of each adjacent level of flare is 10 times different, and there is no upper limit at this level of X.
Flare is one of the most violent activity phenomena on the Sun, with a period of about 11 years, and its main observation characteristics are: the local area of the solar atmosphere suddenly brightens, often accompanied by the enhancement of electromagnetic radiation and particle emission in various energy bands, and the brightness rises rapidly and decreases slowly.
Although the lifespan of a solar flare is only a few minutes to a few tens of minutes, the energy released is equivalent to the total energy of 100,000 or even a million powerful volcanic eruptions, or the equivalent of tens of billions of 100-ton hydrogen bombs**.
And this flare eruption is the second of this year's January 1 x5Level 0 and February 9 x3After the two major explosions of magnitude 3, there was a third flare activity of magnitude X or higher, indicating that the Sun has been quite active recently.
The flare eruption process will release a large number of high-energy particles and strong electromagnetic radiation, which will have a great impact on our earth's geomagnetic activities and the ionosphere and the surrounding space environment.
For example, the X-class flare eruption affected the stability of the Earth's ionospheric structure, causing radio signal absorption events, and the transmission of short-wave radio communications and navigation low-frequency signals was blocked.
Of course, for us, we have the protection of the earth's magnetic field and the atmosphere, and these harmful radiation cannot reach the ground and affect people's health.
An X-class flare eruption can have little or even negligible impact on our planet as a whole, with data showing that during periods of high solar activity, the Earth receives 0 more energy from the Sun than average1%。
However, frequent outbreaks could make this summer even hotter!
According to the forecast of the National Space Weather Monitoring and Warning Center, there is still a possibility of a flare of magnitude above M in the near future.
