The area is called Region 1339 and is being referred to as a “benevolent monster.” 8.3 times bigger than Earth, it generated a solar flare which shot out a burst of charged particles yesterday but - this time - was not aimed at Earth.

However, this extremely active area of the sun will be facing earth for about two weeks. At this time there is no way to predict whether new flares will generate significant solar storms aimed towards Earth and, if so, whether they could result in geomagnetic storms capable of dire consequences on “life as we know it”.
