solar flares sun
Solar flares affect all layers of the solar atmosphere (photosphere, chromosphere, and corona). The plasma medium is heated to tens of millions of kelvin, while electrons, protons, and heavier ions are accelerated to near the speed of light.
Sun Unleashes Monster Solar Flare, Strongest in a Decade. X-class solar flares can cause radiation storms in Earth’s upper atmosphere and trigger radio blackouts, as happened earlier this morning. During large solar flares, the sun can also sling a cloud of energetic plasma from its body, an event called a coronal mass ejection (CME).
Solar Flares. Flare Characteristics Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line
Here’s what’s happened so far. The sun continued to flare on September 5. A solar energetic particle event from the previous day’s activity arrived at the Earth, where it likely affected radio communications as well as the health of satellite systems. On September 6, the sun produced two massive X-Class flares.
Soft x-ray image of a solar flare on the Sun. As the magnetic energy is being released, particles, including electrons, protons, and heavy nuclei, are heated and accelerated in the solar atmosphere. The energy released during a flare is typically on the order of 1027 ergs per second. Large flares can emit up to 1032 ergs of energy.
Sun Erupts With Significant Flare. 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 …
