Strongest solar flare this cycle


Estimated reading time: 2 protocolSolar activity reached moderate levels today, peaking with an M4.44 flare at 13:11 UTC. The solar flare occurred about 8 degrees behind the southeastern edge of the sun. From this we can conclude that the X-ray flux has likely reached more than M4.4. This is the second M-class solar flare of the current solar cycle and the strongest solar flare of this cycle to date.

It is known that long-lasting solar flares like this one are very eruptive. In addition to a type II radio emission, a large amount of plasma was also emitted from the sun, as can be seen in the picture:

Coronal mass ejection after M-class flare

You can see a large and fast coronal mass ejection, both on the coronagraph images from SOHO and the images from STEREO A. The speed of this coronal mass ejection is estimated to be around 1,400 km / s which is very fast. Due to the peripheral location of the eruption, the plasma cloud is directed away from the earth and an impact on our planet is not expected.

Our sun is slowly picking up speed, the exciting phase has begun!
