A Double Solar Flare Just Triggered Radio Blackouts Over Asia And Australia
Sunspot was restless to throw a Double Solar flare on Monday (April 25), triggered several radio blackouts in Asia and Australia.Sunspot Ar2993 erupted with two M1 flares in fast succession, according to spaceweather.com. Solar Flare is an electromagnetic radiation eruption; Flare-M-Class is a medium-sized flare that can interfere with some radio frequencies and sometimes expose astronauts in space to radiation levels that are higher than usual.
Sunspot AR2993 is “Middling size,” Solar Phusicist Dean Pesnell from NASA’s Goddard Space Flight Center told Live Science in the email last week, but hundreds of millions of square miles in the Earth will sit in the active area comfortably. eggs in the nest.
Sunspots is a sun area where the magnetic field is much stronger than the surrounding area. This magnetic power is blocking the flow of hot gas from the solar interior, making spots much cooler than their environment. Solar flare occurs when the magnetic field line near the sunspote-sunspote reorganivated explosively.
Sometimes, this radiation eruption also triggers coronal mass ejection (CMES), which is a sun plasma explosion.It’s been a few weeks busy for the sun, with some active sun spots sending flares. Solar activity occurs in a regular 11 -year cycle, which has been recorded since 1775. The sun is currently in the solar cycle 25 and is in the period of increasing its activity.
Solar Cycle 25 is expected to peak at the end of 2024 or early 2025, which means that the frequency of sun spots, solar flares and CMES is expected to increase.Some of the flares and CMES tend to be more impact than the M1s M1s doubles that have just been folded. Only last week, on April 19 and 20, a different sunspot (AR2992) erupted with strong class X flares.
X-Flare is 10 times as strong as class M flares and can cause radiation storms that interfere with satellites, radio communication and even electricity networks on earth. Fortunately, the earth did not bear the full burden of X-Flare last week, because the sun’s spots did not face directly to this planet.
Large solar flares and CMES can also trigger beautiful auroras further south of the earth’s pole than typical. Solar particles from the sun interact with magnetic fields around the earth, exciting air molecules in the upper atmosphere and cause them to remove photons of light. Results?
