On August 16th, a fairly minor solar flare (class C3) erupted at the spot, and Rogerio Marcon of Sao Paulo, Brazil, caught this picture of the flare in hydrogen-alpha light. (The flare consists of the irregular bright patches. These are the
footprints near the Sun's surface of magnetic fields dumping energy after they reconnected, or "short-circuited," at higher altitudes.)
The flare happened when the spot was facing directly toward us. Therefore the resulting coronal mass ejection should blow by Earth, buffeting our planet's magnetic field, on the 18th or 19th Universal Time, according to Spaceweather.com. As a result, we may get a geomagnetic storm and possible auroras.
