A southern extension of the northern hemisphere polar coronal hole is facing our planet today. It is the same coronal hole that caused minor G1 geomagnetic storm conditions for four days last month.
Yesterday's X8.2 (R3-strong) solar flare from sunspot region 2673 was one of the most spectacular solar flares we have ever seen. Not only was this the second strongest solar flare of the current solar cycle, it also launched an extremely fast and broad coronal mass ejection. What a way to say goodbye! Let's hope it survives its 2 week journey on the far side of the Sun!
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
