New Delhi: The Sun triggered a “significant” solar flare, which was captured by NASA’s Solar Dynamics Observatory (SDO). The flare came from a sunspot named AR2887, which peaked at 11:35 a.m. EDT on October 28, 2021.
The significance of a sunspot is that it determines whether a massive solar flare could have caused any damage to Earth, and depending on its location the flare was located at the center of the Sun and facing Earth, SpaceWeather.com Com said.
NASA tweeted, “Poo! The sun just threw up a mighty glow.”
pow! The sun just served a mighty glow!
This morning at 11:35 a.m. EDT, a powerful X1-class solar flare erupted from the Sun. NASA’s Solar Dynamics Observatory captured all this on camera.
The flare is classified as an X1 category and is likely to hit Earth’s magnetic field on Saturday. According to the US Space Weather Prediction Center (SWPC), the X1-class flare caused a temporary, yet strong radio blackout in the sunlit portion of Earth centered over South America.
The flare produced a massive tsunami of plasma. “The plasma wave was about 100,000 km long and traveled through the Sun’s atmosphere at a speed of more than 1.6 million miles per hour,” SpaceWeather.com said.
Solar flames are powerful bursts of radiation. While the glow of radiation cannot pass through Earth’s atmosphere to harm humans, this really intense glow can disturb the atmosphere in the layer where GPS and communications signals travel.
NASA explained that the X-class reflects the most intense flares, while the numbers provide more information about its strength. An X2 is twice as fast as an X1, an X3 is three times as fast, etc.
