Having already unleashed two X-flares since Sept. 22nd, sunspot AR1302 appears ready for more. The active region has a complex "beta-gamma-delta" magnetic field that harbors energy for strong M- and X-class eruptions. Flares from AR1302 will become increasingly geoeffective as the sunspot turns toward Earth in the days ahead.

"Sunspot complex 1302 is incredibly easy to spot at sunrise or sunset," says Posavec. "Be careful, though. Even the low-hanging sun is bright enough to damage your eyes if you look at it through optics of any kind."
