Our star is becoming active again; it's surface is covered in filaments, there's a handful of nice proms, lots of nice spots and a huge active region that is crackling away with minor flare activity and gradually becoming more geo-effective. In the days ahead expect the aurora borealis to become more likely as the solar wind increases in speed and density. Taken with the DS40 @ f16 with the DMK31.
