One of the most powerful storms in the current climate cycle of the sun It peaked on Wednesday (30th), at 14:37 (GMT), resulting in an X1.3 degree solar flare, one of the strongest in existence. As mentioned fur digital looksunspot AR2975 has been exploding vigorously since Monday (28), ejecting charged particles of radiation.
Solar flares are categorized in a system of letters, with Class C being relatively weak, Class M the most moderate, and Class X being the strongest.

According to Brazilian astronomer Izaac Leite, of Mato Grosso, a Type II radio emission was detected with an estimated speed of 1,424 km/s in activity. “Since the AR 2975 is still in a decent position facing Earth, it is likely that coronal mass ejection (CME) will be guided here,” Light said.
According to SpaceWeather.com, the results of this are already starting to appear a land, with a strong signal that generates a temporary blackout in short-wave radio signals on the American continent. “Pilots, sailors and radio operators may have noticed unusual propagation effects at frequencies below 30MHz,” the site reported a few hours after the flash.

If a coronal mass ejected from the lighthouse and were aimed at Earth, particles laden with radiation could cause auroras in Earth’s atmosphere. Also, according to SpaceWeather, there is circumstantial evidence that the CME is emanating from the Sun, but more observations will be needed to confirm this.
SpaceWeather has revealed that the US Air Force has detected a Type II solar radio explosion that may be related to shock waves from the CME, Light reported. In addition, the Solar Dynamics Observatory (SDO) in NASA I imagined a solar tsunami apparently caused by the CME ejecting from the Sun’s atmosphere. If it collides with the Earth’s magnetic field, strong G3-class geomagnetic storms are expected on Thursday (31). “During these storms, the aurora borealis with the naked eye can descend in the United States as far south as, for example, the states of Illinois and Oregon (50° geomagnetic latitude).”
The sun began its current cycle of solar activity in 2019, and is expected to reach its peak around 2025. Scientists still do not know how active this cycle is, although forecasts indicate fewer sunspots than usual.
Solar activity is constantly monitored by NASA and other space agencies to improve solar weather forecasts. In most cases, coronal mass ejections simply cause auroras as charged particles collide with Earth’s magnetic lines. However, more powerful storms can cause problems with satellites or power lines.
