Solar Activity Increases, Emits Multiple Flares in Succession

WASHINGTON – Activity sun increased by emitting multiple consecutive flares on Monday 25 April 2022. The flare emitted from the AR2993 sunspot with category M1 resulted in blackouts radio in Asia and Australia.

According to spaceweather.com, a solar flare is an eruption of electromagnetic radiation. M-class beacons are medium-sized beacons that can interfere with several radio frequencies. Sometimes it exposes astronauts in space to higher than normal levels of radiation.

Solar physicist Dean Pesnell of NASA’s Goddard Space Flight Center explained that sunspot AR2993 is “medium size,” but is hundreds of millions of square miles across. Sunspots are areas of the sun where the temporary magnetic field is much stronger than the surrounding area.

This magnetic force blocks the flow of hot gases from the sun’s interior, making sunspots much cooler than their surroundings. Sun flares occur when magnetic field lines near sunspots rearrange explosively.

“Sometimes, these radiation eruptions also trigger coronal mass ejections (CMEs), which are solar plasma explosions,” he told Live Science quoted by SINDOnews, Tuesday (26/4/2022).

In recent weeks solar activity has increased, some active sunspots sending flares. Solar activity occurs in regular 11-year cycles, which have been recorded since 1775.

The Sun is currently in the 25th Solar Cycle and is in a period of increasing activity. Solar Cycle 25 is expected to reach its peak in late 2024 or early 2025. This means that the frequency of sunspots, solar flares, and CMEs is expected to increase.
