Solar activity is once again at high levels. Sunspot region 2673 continues to be very active as it rotates towards the west limb. Today (thus far!) it managed to produce a couple of M-class solar flares and an X-class solar flare.
While we were catching some much needed sleep, the coronal mass ejection from Monday's M5.5 solar flare arrived at Earth. Our alert system detected the impact and send out a tweet and a push alert when the shock arrived at DSCOVR around 23:08 UTC.
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!
