Sunspot region 2443 has come to life once more with many C-class solar flares right now and it even managed to produce an impulsive M1.0 (R1) solar flare at 17:52 UTC. This event did not launch a coronal mass ejection.
A trans equatorial coronal hole is now facing Earth. This is the same coronal hole that was responsible for a strong G3 geomagnetic storm on 7 October 2015.
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online.
