Sunspot region 2209, auroral activity
Solar activity increased to moderate levels thanks to an impulsive M3.3 solar flare (R1-minor) from sunspot region 2209 (which was sunspot region 2192 during the previous rotation) at 12:03 UTC. Additional sunspots rotated into view over the past few days and while old sunspot region 2192 is not as large anymore as it once was, it still has some magnetic complexity. We will also take a look at the current geomagnetic conditions and what to expect in the coming days. A coronal hole high speed stream is set to arrive tomorrow and might bring G1 geomagnetic storm conditions.
