According to the weather news site SpaceWeatherin the past time, there have been 19 explosions of the Sun towards the Earth, including 5 medium explosions.

This image from NASA’s Solar Dynamics Observatory shows a group of large sunspots AR2993-94 on the Sun that has rotated its firing range towards Earth. Weather page SpaceWeather The Sun’s “bombardment” is likely to continue.

Class X fire pulses on two nights April 19 and 20 were created from sunspot AR2992. However, scientists were not able to see the full extent of the storm’s activity because of the sunspot on the Sun’s polar edge during the eruption.

According to classification, the Sun’s fire pulse consists of 5 levels: A, B, C, M and X. A degree is the weakest and the X degree is the strongest. The biggest fire in the fire pulse group that took place on two nights April 19 and 20 is rated X2.2.

SpaceWeather said that shortly after the explosion, the US Air Force reported a type II solar radio burst.

The Space Weather Prediction Center at the National Oceanic and Atmospheric Administration (NOAA) confirmed that the flare occurred at 03:57 (GMT) on April 20 and was accompanied by a Type II explosion.

Scientists will use data from the Solar and Heliospheric Observatory (SOHO), a spacecraft operated by NASA and a European partner, to monitor the aurora borealis (CME).

NASA has yet to release details on whether the flare will affect the two active spacecraft.

“Fire pulses and solar eruptions can affect radio communications, power grids, navigation signals, and pose risks to spacecraft and astronauts,” NASA officials wrote in a statement. recently.

The sun appears to be waking up in its latest 11-year cycle of activity. This cycle started in 2019 and is predicted to peak in 2025. Early in the cycle, scientists forecast that the Sun would generally be quieter than usual due to fewer sunspots.
