		<description><![CDATA[The sun emitted its first notable solar flare, peaking in the early morning of 13 January, 2015. Solar flares are powerful bursts of radiation &#8211; a sort of non-visible light. NASA&#8217;s Solar Dynamics Observatory, which watches the sun constantly, recorded this image of the flare. Harmful radiation from a flare cannot pass through the Earth&#8217;s atmosphere to physically affect humans on the ground. However, if the flares&#8217; radiation is strong enough, it can cause problems for communications on Earth and between the Earth and satellites. This flare is classified as an M5.6-class flare. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, and so on.]]></description>
