Sunspot AR3664 remains agitated, continuing its series of explosions this Thursday (9). Between 00:00 and 14:00, the formation released a series of explosions, including two class X, a category that represents the most intense events, reaching their peak at 6:13 am Brasília time.
Solar flares occur when energy stored in solar magnetic fields is suddenly released. In a matter of minutes, they heat the solar plasma to millions of degrees and generate radiation across the entire electromagnetic spectrum.
This time, almost 20 explosions have been recorded since Wednesday morning (8). In the last few hours, our star has produced explosions classified as X 1 and X 2.3, categories that include events capable of causing radio blackouts. The higher the number, the more intense the explosion.
In addition, there have been 15 Class M explosions and another two Class C explosions. In these cases, the effects are less severe, generally resulting in temporary radio blackouts in the Earth’s polar regions. This Thursday (9), radio blackouts were recorded in Europe and Africa.
These phenomena add to others already caused by sunspot AR3664. Since May 3, this region has launched five class X eruptions and another 20 classified as M into space.
Sunspots, like AR3664, are regions on the Sun’s surface that can generate explosions and coronal mass ejections. They stand out for their dark color, indicating lower temperatures than their surroundings, and the quantity in which they appear reflects the level of solar activity.
AR3664 extends almost 20 thousand kilometers from end to end, that is, it is 15 times larger than Earth. Its size is comparable to the spot that caused the Carrington Event, one of the largest geomagnetic storms ever recorded.
