The Sun’s magnetic field undergoes a cycle every 11 years, and it is about to reach the zenith of its activity during this cycle. In other words, the north and south poles of the Sun are inverted. The Sun’s north and south poles then reverse, taking roughly an additional 11 years. The Sun produces a lot of flares during this time that could have an impact on daily life on Earth. Earth is in the line of fire after two enormous solar flares from sunspot region AR3663 just a few days ago.
The first eruption occurred on May 2 and it was an X-class flare, the most powerful category of solar flares, according to space.com. It cause shortwave radio blackouts across Australia, Japan and much of China.
“X FLARE! Sunspot region AR3663 just produced an X1.7 flare, the 11th largest flare so far this cycle. It was an impulsive flare lasting a total of about 25 minutes and peaking at 02:22 U.T,” solar physicist Keith Strong wrote on X.

The second eruption was reported on May 3, which was an M-class flare, the outlet further said.
The newly emerged sunspot has seen a number of flares erupting on the surface of the Sun. At the time of both eruptions, the sunspot was facing Earth and a coronal mass ejection (CME) could have accompanied at least one of these solar flares. CME is a large expulsion of plasma and magnetic field.
According to Space.com, an Earth-directed CME can seriously harm orbiting satellites, power grids, and communication systems in addition to putting astronauts at risk for radiation poisoning.
According to NASA, the reconnection of strong magnetic fields within and surrounding the Sun causes solar flares. They originate from the release of magnetic energy that has accumulated in the solar atmosphere. Flares are categorized based on how strong they are. Following the strongest X-class flares are ten times weaker M-class flares, C-class flares, and lastly B-class flares.
