The Sun just had a very long explosion. Indeed, early on the morning of Tuesday, July 18, the intense activity of our star gave rise to three flares or solar flares, which can cause minor problems on Earth, such as with satellite communications and power grids. According to SpaceWeather.comradiation production of the third and most powerful flare generated sunspot Ar3363 remained at Class M level for a good four hours.
Let’s remember that I flashes Solar radiation is bursts of radiation emanating from the Sun and arriving classified by intensity. Class X, for example, is the most powerful, followed by Classes M and C, B and A, each progressively 10 times weaker. Although the explosion is not the most powerful, it was classified as a letter Mthis was still enough to generate a flux of solar radiation, what how explains The US agency NOOA (National Oceanic and Atmospheric Administration) can interfere with the operation of communication and geolocation systems, disrupting satellite operations and causing radio blackouts.
Geomagnetic storms are coming
And not only that: as observed by the space telescope’s coronagraph Soho NASA and ESA, a powerful flare also caused the phenomenon mass ejection from the solar corona (Cme), running a giant “bubble” of charged particles called plasma. Because radiation emitted by solar flares travels at the speed of light, it reaches Earth fairly quickly, but CMEs and other materials produced by flares travel more slowly through space. Therefore, scientists expect that this explosion will reach the vicinity of the Earth in the near future. July 20 generating geomagnetic storms, although they are not expected to directly hit our planet.
Activity Sun increases and decreases according to the pattern 11 years known as the solar cycle. Scientists track this activity by the number Sunspots it is seen. For example, during solar minimum, months can pass without any sunspots. Current solar cycle, Solar cycle 25began in December 2019 and is expected to peak in 2025 before activity tapers off again.
