An X-flare – the most powerful kind of solar flare – flashed briefly from the sun yesterday (March 29, 2014). It propelled a coronal mass ejection, or CME, into space, the bulk of the CME is due to pass north of the sun-Earth line. However, a faint Earth-directed component could deliver a glancing blow to our planet’s magnetic field on April 1-2, producing beautiful auroras or northern lights.
