The Sun emitted a strong (X-class) solar flare, peaking at 12:52 p.m. EST on March 3, 2023. NASA’s Solar Dynamics Observatory (SDO), which watches the Sun constantly, captured an image of the event.
Solar flares are massive explosions that occur on the surface of the Sun, unleashing tremendous amounts of energy that can cause significant disruptions in various technological systems on Earth. These powerful bursts of energy can cause disturbances in the Earth’s ionosphere, leading to interference with high-frequency (HF) radio communications, satellite navigation signals, and even electric power grids.
In addition, solar flares and eruptions can also pose severe risks to spacecraft and astronauts in space. The release of high-energy particles and radiation during a solar event can damage the sensitive electronic equipment onboard spacecraft and threaten the health of astronauts. In severe cases, these space weather events can cause significant disruptions to critical systems, such as satellite communication and GPS, potentially causing widespread blackouts and other impacts on human activities on Earth.
Scientists and space agencies around the world closely monitor the activity of the Sun and its impact on Earth’s atmosphere and space environment. Sophisticated instruments and satellites are used to study the behavior of the Sun and predict the occurrence of solar flares and other space weather events. Understanding these phenomena is crucial for mitigating the risks they pose to our technology, infrastructure, and space exploration efforts.

Well, is this solar flare heading for Earth? Presumably not, or surely they would have warned us all to duck under our dining room tables.
If a WW3 nuclear holocaust doesn’t get you, our simmering nascent micro nova will in the end!
