The Sun emitted a significant solar flare on April 16, 2022, peaking at 11:34 p.m. EST. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X-Class flare. X-class denotes the most intense flares, while the number provides more information about its strength. More info on how flares are classified can be found here.

Plasma ejections from the sun could cause damage on Earth, scientists say
Washington DC (UPI) Apr 14, 2021
An unusual magnetic storm from the sun will aim at the Earth soon, possibly beginning Thursday, and experts say it has the potential to cause some noticeable damage here on our planet. Scientists say that the solar activity - called a geomagnetic storm - will produce a magnetic discharge and send it in the direction toward Earth. In other words, essentially, that means that increased activity on the sun will eject significant amounts of Coronal Mass Ejection with high-intensity energy toward ... read more
