High-energy X-rays and ultraviolet radiation from a flare are absorbed in our planet's upper atmosphere, and Earth's magnetic field largely deflects solar protons, which helps shield Earth from the most dangerous effects of these solar events. However, solar flares can still have significant eff...
Solar flares are large explosions from the surface of the sun that emit intense bursts of electromagnetic radiation. The intensity of the explosion determines what classification the flare belongs to. The most powerful are X-class flares, followed by M-, C- and B-class; A-class flares are th...

aFigure 8: Features such as solar prominences and solar flares can reach hundreds of thousands of kilometers into space. CMEs are generated as magnetic fields above sunspot groups rearrange. CMEs can trigger events that produce auroras. 图8 : 特点例如太阳突起和日晕可能到达成千上万的公里入空间...
We reevaluate evidence indicating that gamma-ray-line (GRL) flares are fundamentally different from other large flares without detectable GRL emission and find no compelling support for this proposition. For large flares observed by the Solar Maximum Mission (SMM) from 1980 to 1982, we obtain a ...
another doomsday clock continues ticking: solar superflares. Solar flares are commonplace and generally benign. They are outbursts of light and radiation launched from regions of the Sun with intense magnetic fields, whose endpoints are marked on the solar surface by the cooler dark patches known ...
Overall, seven of these regions were responsible for solar flares powerful enough to trigger long-lasting storms on Earth. By monitoring the location and time evolution of each region, the κ-scheme accurately predicted when most of these flares would occur, up to 24 h in advance. The model ...
For a work-a-day spy, beguiling looks are just one of the traits that can give you a leg up on your colleagues, so to speak.
