The sun emits a solar flare; Great photo taken by NASA

NASA’s Solar Dynamics Observatory captured the Sun emitting a fearsome solar flare on April 20, 2022.

Sun, the giant burning ball in our solar system, was caught emitting a solar flare on Wednesday, April 20, 2022. The information was provided by NASA in a blog post. “The Sun emitted a moderate solar flare on April 20, 2022, peaking at 9:59 p.m. ET. NASA’s Solar Dynamics Observatory, which continuously monitors the Sun, captured an image of the event,” the statement said. Nasa. However, this is not the first time the Sun has been captured or observed emitting solar flares. Also earlier on April 16, the hot ball triggered a major solar flare.

“The Sun emitted a large solar flare on April 16, 2022, peaking at 11:34 p.m. EST. NASA’s Solar Dynamics Observatory, which continuously monitors the Sun, captured an image of the event,” the statement said. Nasa. Do you know what a solar flare is? Solar flares are a sudden burst of energy caused by the entanglement, crossing, or rearrangement of magnetic field lines near sunspots.

“A solar flare is an intense burst of radiation from the release of magnetic energy associated with sunspots. Flares are the largest explosive events in our solar system. They are considered bright areas on the sun and can last from Minutes to hours Seeing a solar flare by the photons (or light) it releases, at most all wavelengths in the spectrum X-rays and optical light are the primary ways we monitor flares Flares are also sites where particles (electrons, protons, and heavier particles) are accelerated,” NASA explained.

This solar flare was classified as an M-class flare, NASA said. M-class flares are one-tenth the size of the most intense flares, X-class flares. The number provides information about its strength.

Impact of a solar flare on Earth

According to NASA, flares and solar flares can impact radio communications, power grids, navigation signals, and pose risks to spacecraft and astronauts.

Explaining the impact of the solar flare, the National Oceanic and Atmospheric Administration, Space Weather Prediction Center, said that when a sufficiently strong solar flare occurs, ionization is produced in the lower, denser layers of the ionosphere (the D layer), and the radio waves that interact with the electrons in the layers lose energy due to the more frequent collisions that occur in the higher density environment of the D layer. This can result degradation or complete absorption of HF radio signals. This results in a radio outage – the absence of HF communication, primarily impacting the 3 to 30 MHz band.

Solar flares typically occur in active regions, which are areas of the Sun marked by the presence of strong magnetic fields; usually associated with sunspot groups. As these magnetic fields evolve, they can reach a point of instability and release energy in various forms. These include electromagnetic radiation, which is observed as solar flares.
