M3.7 solar flare from sunspot region 2443
It took a long time but finally sunspot region 2443 seems to deliver. This earth-facing sunspot region produced at 13:52 UTC a long duration M3.7 (R1-minor) solar flare.
Coronal hole effects, M1.9 solar flare
Geomagnetic conditions remain at the minor G1 geomagnetic storming conditions due to the high solar wind speed and a minor southward Bz component of the IMF.
