The scientists also explained that the effects of the coronal mass though weakened, but the potential for further development of geomagnetic storms is still there.
We have corrected the date of the most recent large solar flare.
Also on September 6 the Sun there was another - weaker - flash. 4, 2017. The last one occurred on September 8 while many more are expected to observe in coming days.
"The first flare is classified as an X2.2 flare and the second is an X9.3 flare".
According to the NICT, disturbance in the Earth's magnetic field due to the solar flare peaked between 9 a.m. and noon on Friday. These solar phenomena pop up on the Sun from time to time, sometimes relatively frequently.
Sunspots are cool, dark regions on the Sun's surface with strong magnetic fields. The flash of light and high energy particles released is the solar flare, while the solar matter from the magnetic contortions are CMEs. A failure of telegraph systems was observed through Europe and North America in 1859 because of a massive solar storm.
Gif showing the X9.3 solar flare. In fact, the Sun has a roughly 11-year sunspot cycle - the result of the its changing magnetic field. It turns out, you can actually use the glasses to spot a common - yet fascinating - feature of the sun. As cycles approach its end, solar activity decline. At the end of the active phase, these eruptions become increasingly rare but still can be powerful. Because of this, the Sun alternates between two periods: solar maximum - when sunspots are much more frequent on the Sun's surface - and solar minimum - when the Sun's surface is relatively sunspot free. "We are not quite sure what the consequences of this will be but it's clear that we are in unusual times".
