Today the sun emitted the strongest solar flare of the current solar cycle peaking at 12:02 ET. NASA’s Solar Dynamics Observatory released an image of the event and classified it as a X2.8 flare. The X- class represents the most intense flares, while the number indicates its strength.

Solar flares are bursts of energy caused by intense magnetic fields on the Sun becoming too tangled. The flares can lead to what is known as a Coronal Mass Ejection (CME). The latter causes auroras over Earth’s poles. Such CMEs can trigger dangerous geomagnetic storms if they slam on to Earth. This can affect GPS navigation, air travel, satellites, power grids and communications.
