Major X1.39 solar flare
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.
Coronal mass ejection arrival
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.
