Coronal mass ejection arrival

Coronal mass ejection arrival

The X8.2 coronal mass ejection has arrived. A weak impact was observed at 19:29 UTC with a minor increase in the solar speed, density and the total strength of the interplanetary field (Bt). This is without a doubt the glancing blow arrival of the X8.2 coronal mass ejection as the low energy protons measured by ACE/EPAM peaked at the moment of impact, a classic sign of a CME arrival.

Coronal hole faces Earth

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.

X8.2 coronal mass ejection

X8.2 coronal mass ejection

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!

X8.2 solar flare

Sunspot region 2673 departs in style! The region is now behind the western limb but it still managed to produce it's fourth X-class solar flare: it erupted with an X8.28 (R3-strong) solar flare that peaked at 16:06 UTC.

X9.3 CME impact, Severe G4 storm

The X9.3 coronal mass ejection has arrived at Earth and boy does it pack a punch! While the M5.5 coronal mass ejection turned out to be a huge dissapointment, the X9.3 coronal mass ejection is much stronger than expected and we are seeing some of the strongest geomagnetic storming of the current solar cycle.

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.
