NASA captures the “smile of the sun”: experts warn that geomagnetic storms will hit Earth in dark times
The American website of Fun Science released a report titled “The” Smiling Sun May Hit Earth With A Geomagnetic Storm This Weekend, “said a report that some people say that when you smile, the whole world laughs with you. . But when the sun smiles, the world is immersed in a shower of plasma. This is the unfortunate subtext that emerges when our closest star shows us her adorable “smiley face”.
NASA claims that these happy spots are actually coronal holes – the regions of the corona, the outermost atmosphere of the sun, through which the solar wind travels into space.
Coronal holes, just like sunspots, appear black because they are colder than the surrounding plasma. Through these “cold” portals, the sun’s constant wind of charged particles spills into space at more than 1.6 million kilometers per hour.
Astronomers expect wind of charged particles to hit Earth’s magnetic field on October 29 or 30, potentially triggering a geomagnetic mini-storm. And even the faintest geomagnetic storm, a G1 class, has the potential to disrupt the operation of orbiting satellites and cause small-scale grid fluctuations on Earth.
Despite the friendly smile on the photo, experts warned that the sun’s coronal hole could mean a solar storm is about to “hit” the Earth.
Solar magnetic storm refers to the fact that when the sun’s surface is active, especially during the peak period of sunspots, the number of bursts of glows on the sun’s surface and X-rays, ultraviolet rays, visible light and energetic protons will also increase. and electron beam.
It is reported that during a magnetic storm, satellites are unable to detect the earth for a short time and all electronic devices on earth will be affected.
