The Sunspot has just exploded, sending a large amount of energy towards the Earth
Yesterday afternoon, the remnants of the sunspot (sunspot) just exploded, radiating a lot of solar matter towards the Earth. Dubbed AR2987 by some researchers, the dead sunspot exploded and emitted intense radiation. This is also the source of the phenomenon of “coronal mass ejection – CME”, roughly translated as “halo mass ejection”. True to its name, the CME phenomenon will produce a halo in the Earth’s atmosphere.
The term “black streaks” is used to refer to dark areas on the Sun’s surface, caused by magnetic disturbances originating from the core of the fireball. Black streaks are temporary, with a life cycle lasting from a few hours to several months.
According to Philip Judge, a physicist specializing in the sun, the concept of “dead spots” is more poetic than real. Convection on the Sun’s surface will disintegrate the sunspots, causing magnetic disturbances. “Occasionally, the black streaks can ‘restart’, and appear around them magnetically later (maybe days, or weeks later).,’ researcher Judge said, asserting that the black streak is not so “unlucky”.
Putting aside the future of AR2987 for now, let’s focus on the event just born from the great black streak: at 12:21 pm yesterday in Vietnam time, a strong solar flare of class C was moderate. born from the black streak AR2987. Flares are usually produced when the magnetic and plasma fields above the black spot succumb to pressure, then explode and release energy.
The aurora developments last night were recorded by Twitter account Don Moore.
Class C flares are not rare and rarely affect the Earth directly. There will be times when flare will produce CME coronal mass ejections, when plasma and magnetic fields explode into space at millions of kilometers per hour. Class C flares rarely produce CME, and when they do, CMEs are often slow-flying and low-intensity.
When the CME interacts with the magnetic field enveloping the Earth, charged particles will travel along the magnetic field, reacting with matter in the atmosphere and releasing energy in the form of photons. That’s why the CME makes the atmosphere shine, or we call it the aurora borealis. The intensity of the CME will determine how large the coverage of the aurora is.
At the end of last month, a case burst of solar radiation also interacted with the atmosphere, producing auroras that spread over a large area of the sky.
Yesterday’s CME explosion could generate a mild geomagnetic storm (G1) on April 14. It can affect the operation of satellites as well as the global power grid. At the same time, aurora (visible) can also appear in the sky.
Things like this are nothing to worry about. The researchers think it is a normal reaction of the Sun in cycles, rotating with two strong and weak intervals. Currently, the Sun is going through its 25th cycle – this is the 25th time we’ve measured a period since 1755, when scientists first recorded data on the Sun’s activity.
It is expected that the number of sunspots will peak in 2025, which means we will see more solar storms and more auroras in the near future.
