The Sun never ceases to surprise us. Yesterday, the AR3664 sunspot group unleashed a massive solar eruption, the most powerful of this solar cycle which began between the end of 2019 and the beginning of 2020. This phenomenon, defined as a ‘super–blasting‘, reached a peak intensity rated X 8.7.
Fortunately, there are no new risks storms geomagnetic in sight, given that the region AR3664 it is no longer oriented towards our planet. However, the event caused radio blackouts in several parts of the world, once again demonstrating the impact significant that these phenomena can have on our daily lives.
How is the Sun monitored?
The Sun continues to be the subject of in-depth studies. “The sunspot group AR3664 it is very complex and we expect to see it again in about two weeks,” explains Mauro Messerottiexpert in meteorology space at the University of Trieste. During this time, spots may either fade or intensify, a behavior we cannot predict with certainty at this time.
Experts use the technique of helioseismology to monitor the visible oscillations on the solar surface and discover what is happening in the non-visible part. This method helps us better understand the complex internal workings of the Sun and better prepare for the effects of its changes.
Solar flares are classified by TO to X, with a number following the letter to indicate the specific intensity of the phenomenon. The current super-flare not only does place at the top of this scale for the cycle currentbut it also reminds us of the untapped potential of even more powerful events, such as the historic record of the November 2003.
