What are solar flares? What is a Coronal Mass Ejection (CME)? The plot on this page shows us the most recent 24-hour solar X-ray data from the primary GOES satellite. You can zoom in on this plot by selecting a time period that you wish to view and even export the graph as a JPG, PDF, SVG or PNG file.
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun 's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar ...
Jul 9, 2024 · Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.
The most powerful flare measured with modern methods was in 2003, during the last solar maximum, and it was so powerful that it overloaded the sensors measuring it.
Flashes on the Sun Could Help Scientists Predict Solar Flares.
A solar flare is a tremendous explosion on the Sun that happens when energy stored in 'twisted' magnetic fields (usually above sunspots) is suddenly released. In a matter of just a few minutes they heat material to many millions of degrees and produce a burst of radiation across the electromagnetic spectrum, from radio waves to X-rays and gamma ...

18 hours ago · The intensity of solar flares is categorized by a classification system that uses letters (A, B, C, M, and X), with A being the smallest and X the largest. Within each letter category, there is a finer scale from 1 to 9 that further helps in quantifying the flare’s strength. For instance, an X1 flare is the lowest in the X category but is still a significant event, while an X9 would be among ...
The energy released by a solar flare is millions of times greater than the largest volcanic eruption on Earth or more than a billion megatons of TNT. Solar flares can have real-time effects on our life on Earth, including disrupting satellite and radio communications.
