These radiation flares, which can disrupt communications satellites, Global Positioning System and power grids by reaching the upper Earth atmosphere, were detected and captured by the US Space Agency's Solar Dynamics Observatory.
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.
The massive burst of radiation, one of three so called X-category flares observed over a 48-hour period, continues to produce spectacular aurora displays across northern latitudes.
Solar flares explode when the magnetic field of the sun twists and reconnects.
The same region was also the origin of the mid-level intensity eruptions observed last September 4. That flare was the strongest since 2015, at X2.2, but it was dwarfed just 3 hours later, at 8:02 a.m. EDT (1202 GMT), by an X9.3 flare, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC).
According to NICT, the solar flares that occurred around 9 p.m. on September 6 were about 1,000 times more powerful than normal.
CMS and solar flares are different phenomena but often occur at the same time when it comes to the strongest solar flares. The sun's magnetic field caused the formation of dark sunspots on the star's surface. These are formed when the magnetic field present in the Sun's interior gets deformed, resulting in release of a huge amount of energy into the cosmos. At the moment, we are headed towards a solar minimum. Despite the rare occurrence, cycle end flares tend to be more powerful and explosive. The next solar minimum is expected at some point between 2019 and 2020. Over the last solar minimum (in 2010), sunspots were nearly completely absent for a period of two years-something that had not been recorded for nearly 100 years. Solar cycles last on average eleven years. "We are not quite sure what the consequences of this will be but it's clear that we are in unusual times".
