Sun releases significant solar flare
Oct 30, 2021
Washington [US], October 30 : The Sun emitted a significant solar flare peaking on Friday (local time).
National Aeronautics and Space Administration (NASA)'s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
"The Sun emitted a significant solar flare peaking at 11:35 a.m. EDT on October 28, 2021," NASA in an official press release informed.
Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.
This flare is classified as an X1-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc. Flares that are classified X10 or stronger are considered unusually intense.
NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun's activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth.
