Quote:Improbably, sunspots AR3614 and 3615 exploded in tandem on March 23rd around 0130 UT, directing their fire straight at Earth.
They're called "sympathetic solar flares." Occasionally, magnetic loops in the sun's corona fasten themselves to distant pairs of sunspots, allowing explosive instabilities to travel from one to the other. This has apparently happened to AR3614 and AR3615.
A direct hit could spark strong G3-class geomagnetic storms with mid-latitude auroras in the USA and Europe.
