Yes, the beastly sunspot AR3664 is in the news again.
Although the sunspot has rotated out of our view, it's still quite the hotspot, having fired off its strongest solar flare yet on Tuesday (May 14). Any bursts of solar plasma and magnetic field, known as coronal mass ejections, erupting from AR3664 will now be directed away from Earth, but scientists say there's another planet that could experience impacts from the massive sunspot: Mars.
