Medium-intensity solar flares occur in series

Medium-intensity solar flares occur in series


There was a sequence of solar flares; nine of them are class M, of medium intensity, and most appear to come from a single sunspot

OR Sun released several blasts in the last 24 hours, some even belong to class M, which includes phenomena of medium intensity. Most of the outbursts appear to come from sunspot AR3311, which, thanks to the Sun’s rotation, will soon be pointing towards Earth.




Among the recent solar flares, there was one rated M5.3 on Thursday (18). The sunspot responsible for the new explosions is accompanied by AR 3310, a large sunspot that caused a intense explosion at the beginning of the week.

 

The sequence of phenomena emitted pulses of ultraviolet radiation and X-rays, which took just over eight minutes to reach Earth. Thus, the emitted radiation ionized the upper layer of the earth’s atmosphere, resulting in brief radio blackouts in sunlit regions at the time of impact.

Solar flares occur when magnetic energy builds up in our star’s atmosphere and is released all at once, traveling in a strong burst of electromagnetic radiation. They usually come from areas where there are sunspots, the name given to areas of the solar surface that are cooler and darker than their surroundings.

At the moment, the Sun is heading towards the most active phase of its cycle, which is expected to occur in 2025. Therefore, our star is expected to continue to be more and more active.
